At very high temperatures, as in the environment of a black hole or neutron star, high energy photon interactions with nuclei or even with other photons, can create an electron-positron plasma.

* At the electronic level, absorption in the ultraviolet and visible ( UV-Vis ) portions of the spectrum depends on whether the electron orbitals are spaced ( or " quantized ") such that they can absorb a quantum of light ( or photon ) of a specific frequency, and does not violate selection rules.

At the current CBR photon temperature of, this corresponds to a photon density n < sub > γ </ sub > of around 411 CBR photons per cubic centimeter.

At room temperatures, this photocathode operates with very low dark current, making it ideal for use in photon counting applications.

At least one possible channel of decay must include either a photon, a charged lepton or a meson, each of which would be energetic enough to destroy a nucleus if it strikes one.

2 ) At time t the photon in region A is tested for vertical polarization.

3 ) At this point, the observer in A who carried out the first measurement on photon 1, without doing anything else that could disturb the system or the other photon (" assumption ( R )," below ), can predict with certainty that photon 2 will pass a test of vertical polarization.

5 ) At time t, the observer in A could have decided to carry out a test of polarization at 45 °, obtaining a certain result, for example, that the photon passes the test.

At zero delays, the detection of coincident photon pairs is suppressed.

At the beginning they were limited to the exploration of the Solar System ( see The Land of Crimson Clouds ) but with the invention of photon engine the inter-stellar flights became possible ( see Ruzhena ).

At the top of the hill, atoms are resonant with the other molasses beams, absorb a photon and decay into a lower energy magnetic sub-level, thereby having shed some of their velocity.

* At low energies, the logic of the renormalization group tells us that, despite the unknown choices of these infinitely many parameters, quantum gravity will reduce to the usual Einstein theory of general relativity.

At a spallation source, the time of flight technique is used to sort the energies of the incident neutrons ( higher energy neutrons are faster ), so no monochromator is needed, but rather a series of aperture elements synchronized to filter neutron pulses with the desired wavelength.

At low energies ( around 20 eV ), the interactions between the electrons and the analyte molecules do not transfer enough energy to cause ionization.

At higher energies, the de Broglie wavelength of the electrons becomes smaller than the bond lengths in typical analytes ; the molecules then become " transparent " to the electrons and ionization efficiency decreases.

At the heart of the issue was the teaching of the Essence-Energies distinctions ( which states that while creation can never know God's uncreated essence, it can know His uncreated energies ) by Gregory Palamas.

At low energies, type I string theory is described by the N = 1 supergravity ( type I supergravity ) in ten dimensions coupled to the SO ( 32 ) supersymmetric Yang-Mills theory.

At low energies, type IIA string theory is described by type IIA supergravity in ten dimensions which is a non-chiral theory ( i. e. left-right symmetric ) with ( 1, 1 ) d = 10 supersymmetry ; the fact that the anomalies in this theory cancel is therefore trivial.

At the end of the events of " The Next Life ", the Doctor and his companions escaped the timeless Divergent universe-Rassilon having previously filtered the Zagreus energies out of the Doctor upon his arrival in this universe without the Doctor's knowledge -, but Rassilon and the Kro ' Ka remained trapped in a permanent loop.
