R-matrix calculation of electron collisions with the BF+ molecular ion

Abstract

Electron collisions with the BF+ molecular ion are studied using the framework of the diatomic version of the UK molecular R-matrix codes. A configuration-interaction calculation is performed for BF+ to obtain potential energy curves and target properties for 14 lowest doublet and quartet states. Scattering calculations are performed which yield resonance parameters and excitation cross sections in the energy range 0–20 eV. Cross sections for rotational excitations and an approximate calculation for the electron impact dissociation cross section for BF+ are also presented.
