Electron impact excitation of the states of Ar , Kr and Xe atoms

Abstract

Electron impact excitation of all the and 3 states of argon (n = 3), krypton (n = 4) and xenon (n = 5) from the ground state has been considered in the relativistic distorted-wave approximation. The differential and total cross sections are obtained for incident electrons in the energy range from 15 to 100 eV. The results are compared with the available experimental data and a few theoretical non-relativistic and semi-relativistic calculations wherever possible.
