Inversion of the total cross sections for electron-molecule and electron-atom scattering

摘要

Inverse scattering theory has been applied to construct the interaction potentials from total cross sections as a function of energy for electrons scattered off of atoms and molecules. The underlying potentials are assumed to be real and energy independent and are evaluated using the Eikonal approximation and with real phase shifts determined from the total cross sections. The inversion potentials have been determined using either a high energy limit approximation or by using a fixed energy inversion method at select energies. These procedures have been used to analyse e(sup -) - CH(sub 4), e(sup -)- SiH(sub 4), e(sup -) -Kr and e(sup -) -Xe scattering data in particular. 14 refs., 1 tabs., 3 figs.
