Abstract
The complex-rotation method is used to calculate autoionisation states of H- (1Se, 1P0 and 3P0) below the N=3 hydrogenic threshold. Hylleraas-type wavefunctions are employed and 125 terms for S states and 120 terms for P states are used. The resonance eigenvalue is determined using the technique conjectured by Doolen (1973, 1974).
