    "abstract": "A new state of the H$_2^+$ molecular ion with binding energy of\n1.09$\\times10^{-9}$ a.u. below the first dissociation limit is predicted, using\nhighly accurate numerical nonrelativistic quantum calculations. It is the first\nL=0 excited state, antisymmetric with respect to the exchange of the two\nprotons. It manifests itself as a huge p-H scattering length of $a=750\\pm 5$\nBohr radii.",
