Title: Ro-vibrational states of H$_2^+$. Variational calculations,
Abstract: The nonrelativistic variational calculation of a complete set of
ro-vibrational states in the H$_2^+$ molecular ion supported by the ground
$1s\sigma$ adiabatic potential is presented. It includes both bound states and
resonances located above the $n=1$ threshold. In the latter case we also
evaluate a predissociation width of a state wherever it is significant.
Relativistic and radiative corrections are discussed and effective adiabatic
potentials of these corrections are included as supplementary files.
