Elastic electron collision cross sections for ammonia molecules in the energy range 0.1-1.0 keV
Abstract
Elastic differential, integral, and momentum-transfer cross sections are calculated for the e-NH3 system in the energy range of 0.1-1.0 keV. A parameter-free spherical optical potential is constructed from near-Hartree-Fock one-center expansion ammonia wave functions. The optical potential is then treated in a partial-wave analysis to extract various cross sections. Several versions of parameter-free polarization and exchange potentials are employed. The calculated differential cross sections are compared with the available experimental data.
