Photodetachment of an electron bound by a zero-range potential in magnetic fields of arbitrary strength.

Abstract

The model problem of photodetachment of an electron initially bound by a zero-range potential in a homogeneous static magnetic field of arbitrary strength is solved exactly. Expressions for the cross sections are derived within the nonrelativistic theory for various photon polarizations. In particular, photodetachment from states that exist only in the presence of a magnetic field is studied. In the limit of small fields the results obtained agree with findings of other authors.
