Abstract

A method for obtaining the discrete component of resonance states in negative molecular ions is described. It is based on standard MRD-CI type calculations and especially designed for treating larger molecular systems. The resonance is thereby stabilised by increased nuclear charge. The method is applied to the calculation of N2- in its 2 Pi g( pi u4 pi g) and 2 Pi u( pi u3Ss2) resonance states.
