Abstract
This work reports on differential, integrated and momentum transfer cross sections for the elastic scattering of electrons and positrons off the ions of nitrogen isonuclear series (N+ - N7+) over the energy range 1–500 eV. Calculations of these observable quantities involve the solution of Dirac relativistic wave equation employing a pure Coulomb potential and a short range potential. The latter comprises static, exchange, polarization and absorption potentials. Effects of these individual potentials on angular distribution of elastically scattered electrons are investigated throughout this ionic series. Differential cross sections for electron and positron scattering are compared with each other to demonstrate the difference of their collision dynamics. A satisfactory agreement between our predictions and other available data, experimental and theoretical, is observed.
