Electron scattering from Ne II using the relativistic R-matrix method

Abstract
The R-matrix method for electron scattering from atoms and ions using the Dirac Hamiltonian has been programmed and a test case of electron scattering from Ne II is considered. The agreement for the total cross section between the relativistic calculation and previous non-relativistic calculations is excellent. The relativistic calculation enables cross sections for transitions between fine-structure levels to be obtained.
