Abstract
A detailed investigation of the long-lived states of the hydrogen molecule anion has been performed within the ab initio–based nonlocal resonance model. The resonances in the electronic state of are stabilized against autodetachment by molecular rotation and can be interpreted as orbiting states of with high angular momenta . The lifetimes and energies of all long-lived states have been calculated for the hydrogen molecular anion and its isotopic analogs. Recent experimental values of Heber et al. [Phys. Rev. A 73, 060501(R) (2006)] for lifetimes of , , and can be explained within the model. For , we predict a large number of states with lifetimes up to .
