Elastic Scattering of Electrons on Fluorine Atom

Abstract

The B-spline R-matrix (BSR) method is used to study electron collisions with neutral fluorine over an energy range from threshold to 110 eV. This method allows to use the term-dependent nonorthogonal orbitals along with B-splines as basis functions. Thus, it provides the effective accounting of electron correlation. The differential cross sections (DCS) of electron impact elastic scattering on fluorine atom in the considered energy range are calculated. The close coupling (CC) expansion included 39 bound states of the F atom. Energy-angular dependences of DCS for the elastic e−F scattering were obtained and corresponding 3D surfaces of DCS were constructed. The behavior of the DCS angular dependences for elastic e−F collisions with energy changing is discussed.
