摘要：
The parameter that determines the nondipole correction to the angular distribution is calculated for Ar is and 3s subshells in the Hartree-Fock (HF) approximation and taking account of the multielectron correlations, using the random-phase approximation with exchange. In the photoelectron energy range 0-100 eV the parameter, which for s subshells is nonzero at threshold, is found for Ar 3s to be strongly affected by multielectron correlations. Results are also presented for He and Be in the HF approximation. [S1050-2947(99)50804-4].
