Abstract:	Two resonances in the photodetachment spectrum of H-, one just below the n=3 threshold and the other just below the n=4 threshold, were observed decaying into H0(n’=2)+e. The n=3 resonance shows a preference for the n’=2 channel when compared with total-detachment measurements. Fano-line-shape fits give central energies of 12.652±0.003 eV for H-(3) and 13.338±0.004 eV for H-(4). These values are in good agreement with current theoretical calculations.
