Study of the relationship between principle quantum number of H atom and single differential cross section for electron emission in proton-H atom collision

الملخص EN

Single differential cross section (SDCS) has been calculated for electron emission in collision of different Protons energies with Hydrogen atom for electrons emission energies (1-1000 eV).

SDCS has been calculated for ground state (n = 1) and exited states (n = 2, 3).

SDCS for n = 1 level less than SDCS for n=2, 3 levels at the range of electron energy less than 10eVand SDCS"s for different levels have the same values at the electron energy more than 10eV.

SDCS as a function to the binding energy (where the binding energy for nth-level for H-atom 221nEb = in atomic units) has been studied.

The SDCS is independent on large principle quantum number and it is decreasing with impact energy.
