New ficticious force in electron-atom/ion scattering — •Hubert Klar — DHBW Lörrach

We treat two-elctron atoms (like He) in the nonrelativistic frame. We derive for the e-e interaction a momentum-dependent ficticious force in addition to the electrostatic interactions. In contrast to other ficticious forces in mechanics our force constitutes an entirely new quantum effect. The diffraction of an electron wave from the three-body Coulomb potential surface induces an e-e force. This effect has only little influence onto the lower part of the spectrum, and was therefore overlooked sofar. High double excitation, however, changes dramatically.
