Electron collision with Ammonia and phosphine at wide range of energies
The NH3 and PH3 molecules achieve differential electron elastic scattering cross-sections for energies ranging from 15 eV to 500 eV for ammonia and from 5 to 500 eV for phosphine. Calculations are performed using partial waveforms describing the target molecule using a single Hartree-Fock Molecular...

| Summary: | The NH3 and PH3 molecules achieve differential electron elastic scattering cross-sections for energies ranging from 15 eV to 500 eV for ammonia and from 5 to 500 eV for phosphine. Calculations are performed using partial waveforms describing the target molecule using a single Hartree-Fock Molecular Function Center. The potentials used include a constant part—numerically obtained from quantum computation in addition to subtle effects such as correlation, polarization, and potential exchange, results of this model clearly show the role of the exchange, as well as the contributions of correlation and polarization, especially at low scattering angles and incident energies. The differential cross-sections obtained were compared with a large amount of experimental data from the research, and good agreement was found. Throughout the scattering angles and power ranges examined here.
