The B-spline R-matrix method in low-energy electron scattering on complex atoms

Abstract

This paper provides an overview of the systematic application of the Bsplines R-matrix method (BSR) to calculate of electron-atom collision processes. This method allow to use the term-dependent nonorthogonal orbitals along with B-splines as basis functions. Thus, it provides the effective accounting of electron correlation. The cases of the slow electrons scattering on the Ca, Mg, Sr, Si, F, Al, and B atoms have been considered. The obtained calculations results are in good agreement with a large set of experimental data in a wide range of collision energies.
