We have applied a new method for computing properties of molecular negative ion resonances to calculate the potential curves of the first three /sup 2/..sigma../sup +//sub u/ states of H/sup -//sub 2/. The energy widths and lifetimes of the resonances are also calculated. The first and third resonances correlate to H+H/sup -/ asymptotes at R = infinity, but the second resonance disappears near R = 6.0 a.u. The resonance properties are shown to be insensitive to variations in the basis set. The results are compared to recent calculations on this system.
