A new vibrational level of the $H^{+}_{2}$ molecular ion

Abstract

A new state of the H2+_2^+2+​ molecular ion with binding energy of 1.09×10−9\times10^{-9}×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±5a=750\pm 5a=750±5 Bohr radii.
