Studies of cross sections for collisions of electrons from hydride molecules:NH3andPH3

Abstract

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 $\mathrm{N}{\mathrm{H}}_{3}$ and $\mathrm{P}{\mathrm{H}}_{3}$ 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.
