A new vibrational level of the H2+ molecular ion
Abstract
A new state of the H2+ molecular ion with binding energy of 1.09×10-9 a.u. below the first dissociation limit is predicted, using highly accurate numerical nonrelativistic quantum calculations. It is the first L=0 excited state, antisymmetric with respect to the exchange of the two protons. It manifests itself as a huge p-H scattering length of a=750 5 Bohr radii.
