摘要 The relative photodetachment cross section for decay into the H(N=2) channel by the 1P° shape resonance in H- was measured, as well as that for decay into all channels. The branching ratio σ(N=2)/σ(total) was computed for a series of energies between 10.95 and 11.3 eV after normalizing the cross sections to theoretical peak amplitudes. The maximum branching ratio (≊0.8) appears at an energy about 20 meV higher than the central energy of the resonance. Results are compared with recent theoretical calculations.
