Scattering of electron and positron by atomic nitrogen and its application in transport characteristics
A theoretical investigation of electron and positron scattering from atomic nitrogen over the incident energy range from 1 eV to 1 MeV is presented. Scattering observables, including integrated elastic, momentum transfer, inelastic, ionization, and total cross sections, as well as the Sherman function, are calculated by solving the Dirac relativistic partial-wave equation with a local complex optical potential. Critical minima in the elastic differential cross section and corresponding maxima in the predicted spin polarization are examined in detail. The calculated cross section set is subsequently employed in a Monte Carlo simulation to determine electron transport properties in nitrogen gas for reduced electric fields (E/N) from 1 to 500 Td. Results for the drift velocity, mean energy, and longitudinal diffusion and mobility coefficients are presented and discussed.
