When an electron in an atom falls from higher orbit to a lower orbit a photon gets emitted. Since the electrostatic potential-energy of the electron is negative, because of the attractive force between the proton and the electron, the fall of electron makes its potential-energy more negative....
Correlations between the arrival time and the energy of photons emitted in outbursts of astrophysical objects are predicted in quantum and classical gravity scenarios and can appear as well as a result of complex acceleration mechanisms responsible for the photon emission at the source. This paper ...

The registration of the escape from a potential well either by TA or MQT significantly depends on the damping in the resistive state. Within the framework of the mechanical analog of the RCSJ model, which considers the motion of a particle in a washboard potential, the system stops in the n...
One of the methods for studying the highest energy cosmic rays is to measure the fluorescence light emitted by the extensive air showers induced by them. T... M Giller,A ?Mia?Kowski - 《Astroparticle Physics》 被引量: 19发表: 2012年 Observations of ultra-high-energy photons from Cygnus X...
Within this picture, harmonic photons are emitted as a result of electrons following trajectories such that they recombine with their parent ion. We assume that an electron is photo-excited to the conduction band of the liquid at time tion. Following this, the Newtonian equations of motion can ...

4A), while upconverting layers are positioned at the bottom of the solar cell and the emitted light is reflected toward the top of the cell by an additional reflection layer (Fig. 4B). Both designs generate inconveniencies. The DS and DC layers are often highly reflective so that reflection...
Recoilless resonant capture of monoenergetic electron antineutrinos (Moessbauer antineutrinos) emitted in bound-state beta-decay in the system 3H - 3He is discussed. The recoilfree fraction including a possible phonon excitation due to l... W Potzel - 《Journal of Physics Conference》 被引量: ...
In the decay process, a particle with a lower energy level is generated while excessive energy is emitted. There are three types of emissions that determine the decay process in particles with different levels of stability. The alpha (α) particles denote the dense and positively charged particles...
