The nondipole corrections to the dipole approximation for the angular distribution of photoelectrons are calculated for Ar 3s subshell in the Hartree-Fock (HF) approximation for photoelectron energies ranging from threshold to 2 keV. The effects of electron correlation which are very important have been taken into account using the multiconfiguration HF approximation. It is found that near the threshold from 0 to 50 eV photoelectron energy, the nondipole parameters show oscillatory structure due to large electron correlation effects. The results are compared with existing theoretical and experimental data.
