Electron collision studies on the CH2+ molecular ion

Abstract

Abstract Calculations are performed for electron collision with the methylene molecular ion C H 2 + in its bent equilibrium geometry, with the goal of obtaining cross sections for electron impact excitation and dissociation. The polyatomic version of the UK molecular R-matrix codes was used to perform an initial configuration-interaction calculation on the doublet and quartet states of the C H 2 + ion. Subsequently, scattering calculations are performed to obtain electron impact electronic excitation and dissociation cross sections and, additionally, the bound states of the CH2 molecule and Feshbach resonances in the e- C H 2 + system.
