Scattering of e± from the neon isonuclear series over the energy range 1 eV–0.5 GeV

Abstract

This work calculates the differential, integral and momentum transfer cross sections for the scattering of e± by the neutral neon over the energy range 1 eV–0.5 GeV and those of e− by the ions (Ne+–Ne10+) over the range 1 eV–1 keV. It also includes the estimation of the viscosity, inelastic, total and total ionization cross sections and Sherman function for the e±-atom systems over the same energy range. Our calculations involve two approaches, the optical potential model (OPM) and the nuclear structure approach (NSA), depending upon the collision energy. Both the approaches employ Dirac partial wave analysis but differ in the potentials. In OPM, a complex projectile-target optical potential, comprising static, exchange, polarization and imaginary components, is employed. In the NSA, only the nuclear potential is used, neglecting the screening of the electrons. Moreover, we have determined positions of critical minima, in energy and angle, from the analysis of elastic differential cross sections and Sherman function at different energies. Our results agree reasonably well with the available experimental data and other theoretical calculations.
