设散射前电子总能量为E1，动量大小为P1，散射后总能量为E2，动量大小为P2；散射前质子总能量为E0，散射后总能量为E，动量大小为P；由动量守恒有：P1^2+P2^2-2*P1*P2cos5度=P^2 (1)由能量守恒有：E=E1+E0-E2，两边平方得E^2=E1^2+E0^2+2*E1*E0+E2^2-2*E1*E2-2*E0*E2 代...
The total energy of an electron is calculated if we know its speed. The below expression best explains the total energy of an electron. E=γmc2 Where, The relativistic factor is γ m shows the mass of the electron, and c is the speed of light ...
A convenient unit of energy for atomic and subatomic systems. It is equivalent to the energy acquired by an electron when it falls through an electric potential of 1 volt 电子伏特 (eV)。 能量一个方便单位为原子和亚原子的系统。 当它通过1伏特时,电潜力下跌它与电子获取的能量是等效的 [translate...
The electron spectrum in space is almost always steeply falling with energy, so that the flux at energies >100 keV that causes charging of internal materials is much less than the low energy flux. The total charging current becomes much smaller and the charging process slows down to time scale...

The core-electron binding energies (CEBEs) of dioxolane37and five other C3H6O2structural isomers were computed at the DFT level and were compared with X-ray photoelectron spectra (Scheme 26) [00IJQ44a]. The results are in a good agreement with an average deviation of 0.15eV. MP2/6-311G(...
Density functional theory (DFT) calculations reveal that the Au-induced tensile strain on Pt-Co shell can not only boost the adsorption and dissociation kinetics of water at Co site by upshifting the d-band and promoting the electron transfer, but also downshift the d-band center of Pt in ...
