However, if the excited atom has been previously ionized, in particular if one of its inner shell electrons has been removed, a phenomenon known as the Auger effect may take place where the quantity of energy is transferred to one of the bound electrons causing it to go into the continuum.

In short, the electrons of the atoms in the atomizer can be promoted to higher orbitals ( excited state ) for a short period of time ( nanoseconds ) by absorbing a defined quantity of energy ( radiation of a given wavelength ).

The ease with which electrons in the semiconductor can be excited from the valence band to the conduction band depends on the band gap between the bands.

These perturbations result in different arrangement of electrons in the excited state of the involved molecules and therefore in different effects.

When they struck atoms in the glass wall, they excited their orbital electrons to higher energy levels, causing them to fluoresce.

Electronic band theory ( a branch of physics ) says that a charge will flow if states are available into which electrons can be excited.

There is always some voltage ( called the breakdown voltage ) that will give the electrons enough energy to be excited into this band.

The gain medium absorbs pump energy, which raises some electrons into higher-energy (" excited ") quantum states.

For example, in internal conversion decay, the energy from an excited nucleus may be used to eject one of the inner orbital electrons from the atom, in a process which produces high speed electrons, but is not beta decay, and ( unlike beta decay ) does not transmute one element to another.

Increasing the intensity of the light beam increases the number of photons in the light beam, and thus increases the number of electrons excited, but does not increase the energy that each electron possesses.

Indeed, even if the photoelectric effect is the favoured reaction for a particular single-photon bound-electron interaction, the result is also subject to statistical processes and is not guaranteed, albeit the photon has certainly disappeared and a bound electron has been excited ( usually K or L shell electrons at nuclear ( gamma ray ) energies ).

The excited electrons lost from chlorophyll in photosystem I are replaced from the electron transport chain by plastocyanin.

When sodium or its compounds are introduced into a flame, they turn it yellow, because the excited 3s electrons of sodium emit a photon when they fall from 3p to 3s ; the wavelength of this photon corresponds to the D line at 589. 3 nm.

The ease with which electrons in the semiconductor can be excited from the valence band to the conduction band depends on the band gap.

Electrons at these states can be easily excited to the conduction band, becoming free electrons, at room temperature.

Atoms also have distinct x-ray spectra that are attributable to the excitation of inner shell electrons to excited states.

These excited electrons can tunnel across the barrier.

Cathodoluminescence, the emission of light when atoms excited by high-energy electrons return to their ground state, is analogous to UV-induced fluorescence, and some materials such as zinc sulfide and some fluorescent dyes, exhibit both phenomena.

Low-frequency light only ejects low-energy electrons because each electron is excited by the absorption of a single photon.

Increasing the intensity of the low-frequency light ( increasing the number of photons ) only increases the number of excited electrons, not their energy, because the energy of each photon remains low.

Underlying the spectroscopic technique is the Auger effect, as it has come to be called, which is based on the analysis of energetic electrons emitted from an excited atom after a series of internal relaxation events.

The Auger effect is an electronic process at the heart of AES resulting from the inter-and intrastate transitions of electrons in an excited atom.

Physicists showed in the 1920s that in gas at extremely low densities, electrons can populate excited metastable energy levels in atoms and ions which at higher densities are rapidly de-excited by collisions.

These gain media could release stimulated emissions between an excited state and a lower excited state, not the ground state, facilitating the maintenance of a population inversion.

Such reactions can lead to the formation of triplet excited species, which release photons upon returning to a lower energy level in a process analogous to phosphorescence.

Boy George, however, was more excited about his future projects like his record label, More Protein, and his dance-oriented music he was looking to release.

" Gerard Cosloy was excited by the completed album, but was devastated when Mascis told him the band was going to release it on SST Records.

As a result of the bipolar cell being hyperpolarized, it does not release its transmitter at the bipolar-ganglion synapse and the synapse is not excited.

For example, in the decay of an excited state of the nucleus of < sup > 125 </ sup > I, 7 % of the decays emit energy as a gamma ray, while 93 % release energy as conversion electrons.

The nuclei get " excited " in the process, and emit gamma rays to release the extra energy so they can return to their normal rest state.

In 2003 his novel Esra excited attention when its sale was prohibited shortly after its release.

Many prisoners report being anxious about their release ; they are excited about how their life will be different “ this time ” which does not always end up being the case.

Unfortunately, John's father is so excited that the beast is dead that he forgets to release the hound and rushes out to congratulate his son.

Clint Lowery posted the following statement ; " We're very excited about the new DARK NEW DAY release.

A restaurant posted a reminder to patrons `` who became excited and left without paying their checks ''.

When the excited atoms relax back into their ground state, a low-intensity glow is emitted, giving the technique its name.

Sometimes these were positioned with their backs to the battle so as not to get unduly excited.

In most lasers this medium consists of population of atoms which have been excited into such a state by means of an outside light source, or an electrical field which supplies energy for atoms to absorb and be transformed into their excited states.

Disillusioned with the capitulation of the social democrats, excited by the emergence of workers ’ councils, and slowly distanced from Leninism, many communists came to reject the claims of socialist parties and to put their faith instead in the masses.

He prided himself on his ancient Etruscan lineage, and claimed descent from the princely house of the Cilnii, who excited the jealousy of their townsmen by their preponderant wealth and influence at Arretium in the 4th century BC.

In spectroscopy one can frequently find that atoms or molecules in the excited states dissipate their energy in the absence of any external source of photons.

They are particularly strongly excited when their source is close to the surface of the Earth, as in a shallow earthquake or explosion.

In this context, the work of the explorers is akin to that of psychotherapists in their exploration of psychological structures excited by historic traumas.

These oscillators give their entire energy to the electromagnetic field, creating a quantum of light, as often as they are excited by the electromagnetic field, absorbing a quantum of light and beginning to oscillate at the corresponding frequency.

When the photons belonging to the signal at a different wavelength from the pump light meet the excited erbium atoms, the erbium atoms give up some of their energy to the signal and return to their lower-energy state.

Using argon bubbles in sulfuric acid, their data show the presence of ionized molecular oxygen O < sub > 2 </ sub >< sup >+</ sup >, sulfur monoxide, and atomic argon populating high-energy excited states, which confirms a hypothesis that the bubbles have a hot plasma core.

They found and copied several and were particularly excited about their final discovery, which Grove described thus: " I found, at the bottom of the cupboard and in its farthest corner, a bundle of music books two feet high, carefully tied round, and black with the undisturbed dust of nearly half-a-century.

And the geographer, as he turns over the folios, with their details of population and of arable, woodland, meadow and other resources, cannot but be excited at the vast amount of information that passes before his eyes.

The contents of ' De motu ...' so excited Halley by their mathematical and physical originality and far-reaching implications for astronomical theory, that he immediately went to visit Newton again, in November 1684, to ask Newton to let the Royal Society have more of such work.

Gregory's hagiographies are also an invaluable source of anecdotes and stories which enrich our understanding of life and belief in Merovingian Gaul, whilst it is fascinating to study works such as these which must have excited their audience to such an extent.
