Studies of cross sections for collisions of electrons from hydride molecules: NH3 and PH3

摘要

A parameter-free spherical complex optical potential approach in the fixed-nuclei approximation is applied here to calculate elastic differential, integral, and momentum-transfer cross sections as well as total (elastic plus inelastic) cross sections for the scattering of electrons from NH3 and PH3 molecules (i.e., nonmetallic hydrides) in the electron energy range of 0.1-100 eV. The projectile-target interaction is represented by a sum of a real and an imaginary potential. Present calculated results are compared with the available calculations and the experimental measurements. The quantitative features of the scattering parameters (such as Ramsauer-Townsend minimum and shape resonance structure), as observed in experiments, are well reproduced in the present study.
