摘要：

Higher multipole corrections to the dipole-approximation result for angular distributions of photoelectrons at low photon energies are discussed. The first-order corrections lead to a simplified formula for the angular distribution, which extends the dipole results for linearly, unpolarized, and partially polarized light. It is shown how atomic parameters can be obtained from experimental measurements, and relationships to previous work on photoelectron angular distributions are discussed briefly. © 1990 The American Physical Society.
