Abstract
A metastable molecular dianion C-2(2-) in a closed-shell (1) Sigma(g)( +) state has been found. Using a complex absorbing potential in conjun ction with a multireference configuration interaction wave function, t he resonance position and width are calculated and their dependence on the nuclear charge Z is examined. Based on our findings the interpret ation of a recent scattering experiment is questioned and an alternati ve experiment is proposed.
