After decades of growing interest in and development of experiential education and scouting ( not Scouting ) in the United States, and the emergence of the Scout Movement in 1907, in 1910 Boy Scouts of America was founded in the merger of three older Scouting organizations: Boy Scouts of the United States, the National Scouts of America and the Peace Scouts of California.

After initial development, Robinson turned the movement over to James E. West who became the first Chief Scout Executive and the Scouting movement began to expand in the U. S. As BSA grew, it absorbed other Scouting organizations.

After the detonation of the first Soviet fission bomb in August 1949, he, along with Isidor Rabi, wrote a strongly worded report for the committee which opposed the development of a hydrogen bomb on moral and technical grounds.

After World War II, despite censorship, filmmakers like Roman Polanski, Krzysztof Kieślowski, Agnieszka Holland, Andrzej Wajda, Andrzej Żuławski impacted the development of the cinematography.

After the Gatling gun was replaced in service by newer recoil-or gas-operated non-rotating machine guns and automatic cannons, the approach of using multiple rotating barrels fell into disuse for many decades, reappearing after World War II with the development of the M61 Vulcan.

After the end of World War II, Italy was in rubble and occupied by foreign armies, like Germany and other Axis powers, a condition that worsened the chronic development gap towards the more advanced European economies.

After a largely informal process within elite circles in which ideas were discussed and developed, steps might be taken to institute more formal policy development.

After several years in development, Ramone's second posthumous album was released on May 22, 2012.

After development of Kazaa Lite stopped, K-Lite v2. 6, Kazaa Lite Resurrection and Kazaa Lite Tools appeared.

After Nintendo's action-adventure Metroid had been finished, more staff members were alloted to the development of Kid Icarus.

After a statistically sufficient quantity of time, an electron in an excited state will undergo a transition to a lower state.

After finding the quantized character of charge, in 1891 George Stoney proposed the unit ' electron ' for this fundamental unit of electrical charge.

After an electron absorbs a high energy photon the system is excited electronically and vibrationally.

After absorption and re-emission of the energy, many wavelengths may emerge due to Stokes shift and various electron transitions.

After a statistically sufficient quantity of time, an electron in an excited state will undergo a transition to a lower state via spontaneous emission.

After scattering, the possibility that the electron might be accelerated to a significant fraction of the speed of light, requires that its total energy be represented using the relativistic energy-momentum relation:

After investigation, it was realized that the muon did not have the expected properties of a meson, but rather behaved like an electron, only with higher mass.

After the reaction, ignited by electron beams in this case, the magnet funnelled the hot gas to the rear for thrust.

After nuclear reactions that result in an excited nucleus, the energy that must be radiated or otherwise removed as binding energy for a single nucleus may be in the form of electromagnetic waves, such as gamma radiation, or it may appear in the kinetic energy of an ejected particle, such as an electron, in internal conversion decay.

After completing his PhD in 1933, Ruska continued to work in the field of electron optics, first at Fernseh Ltd in Berlin-Zehlendorf, and then from 1937 at Siemens-Reiniger-Werke AG.

After the system has returned to equilibrium, let the change in the electron density and electric potential be Δρ ( r ) and Δφ ( r ) respectively.

After World War II, Ruska resumed work at Siemens, where he continued to develop the electron microscope, producing the first microscope with 100k magnification.

Energy level s for an electron in an atom: ground state and excited state s. After absorbing energy, an electron may Atomic electron transition | jump from the ground state to a higher energy excited state.

After the RF energy has been extracted from the electron beam, the beam is destroyed in a collector.

After fracture, the first change seen by light and electron microscope is the presence of blood cells within the tissues adjacent to the injury site.

After Fowler-Nordheim theoretical work in 1928, a major advance came with the development in 1937 by Erwin W. Mueller of the spherical-geometry field electron microscope ( FEM ) ( also called the " field emission microscope ").

After an electron absorbs a photon of high energy, it may undergo vibrational relaxations and intersystem crossing to another spin state.

After absorbing energy, an electron may jump from the ground state to a higher energy excited state.

After the IC electron has been emitted, the atom is left with a vacancy in one of its electron shells, usually ( as noted ) an inner one.

After the requirement of an “ ether ” which propagates light waves had been abandoned, there was considerably less difficulty in accepting this same idea when the observed wave properties of the electron suggested the introduction of a new field.

After working for Philips Research in Eindhoven on high-voltage equipment for electron microscopy for a few years, he joined CERN in 1956 where he stayed until his retirement in 1990.
