摘要
The photodetachment of H- near the H(N = 4) and H(N = 5) thresholds in an external electric field is studied theoretically. The recently observed photodetachment threshold shifts by Halka et al. are interpreted in terms of the shifts of the barrier heights of the hyperspherical potential curves as the electric field strength is varied. It is shown that higher members of the zero-field Feshbach resonances can emerge as field-induced shape resonances in an electric field.
