INTERACTION OF ELECTRONS WITH ATOMS IN-GROUND AND EXCITED-STATES - POTENTIAL OF INTERACTION, MOMENTUM-TRANSFER CROSS-SECTIONS

In this paper the potential of the electron-atom interaction was prese nted which may be useful both in the case of the ground state of an at om with one optical electron and in the case of the excited state of a ny atom, and which is given by expressions suitable for operational us e. The presented potential is used in calculating the transport cross sections for the elastic electron scattering on the atoms of H, Li and Na respectively, in the ground and excited states.
