Screened hydrogenic functions
WebUsing plane waves to describe the incident and scattered particles, and screened hydrogenic and Coulomb functions to describe the atomic electrons before and after ejections, we have calculated the differential and total ionization cross sections of 11 atoms and one ion by electron impact, and ionization of helium by proton impact. The effective … WebThe Screened Hydrogenic Model (SHM) is an alternative approach that uses the one-electron wavefunctions of the hydrogen atom for each electron of a mul-ti-electron atom by substituting an effective nuclear charge Z i for the value of Z. Agreement with experimental energies can be obtained by varying Z i with screen-ing parameters.
