In this paper we present an empirical relation for total stopping power keV in terms of total energy (kinetic energy + rest mass energy) for electrons and positrons from 20 keV to 50000 and have been fitted by a
The projectile and target dependence of absolute cross-sections for binary encounter-, Auger - and backward-emitted electrons are analyzed.doi:10.1140/epja/i2007-10387-4E. De FilippoG. LanzanòH. RothardC. VolantA. AnzaloneN. ArenaM. Geraci...
Therefore, scientists turn their attention to the electride, which not only could donate electron for the adsorbed N2, but also trap excess electrons to form the hydride. For instance, Pd hydrides could serve as an electrocatalyst for the N2 fixation under ambient conditions.47 The high ...
The electron emission process itself is simulated by including the associated transport, inherent scattering and exchanges of energy and momentum within the target, with eventual escape of electrons over the work function barrier at the surface. Monte Carlo simulations are used to model electron ...
Upon irradiation of visible light there will be successive generation of electron (e−) and hole (h+) pair in the valence band (VB) and electrons will jump to conduction band (CB) with excessive energy. Added HAuCl4 undergoes photoreduction to Au(0) by these photogenerated electrons and ...

Gold has a high ionization potential, it is difficult to lose the outer electrons into positive ions, also not easy to accept electrons into anions, its chemical properties are stable, and other elements weak affinity. Therefore, in nature is the existence of elemental gold state...
How many protons, neutrons, and electrons does a neutral hydrogen atom have? What is its atomic number and atomic mass? Which element has 32 protons? How many neutrons and electrons does a neutral atom of this element have and what is its mass number?
The phenomenon behind these types of materials is related to the collective oscillations of conduction band electrons in metal NPs upon excitation with incident light at a wavelength of about one order of magnitude larger than the NP size [6,7]. Coupling of the incident light to the so-called...
In atomic physics regime (at collision energies Ei from eV to MeV), interaction of incident lepton with the atomic electrons and nuclear protons and the screening of the nuclear charge by the surrounding electrons plays a dominant role in collision dynamics. At Ei≥ 15 MeV, this interaction is...
