The photoelectron angular distribution asymmetry parameter beta for 3s electrons of atomic chlorine has been calculated using the multiconfiguration Hartree-Fock method for both bound and continuum wave functions. It is determined in the electric dipole approximation within the framework of the angular-momentum-transfer formulation. The effects of electron correlation are investigated, and it is shown that electron correlations are very important for beta values corresponding to both P-3 and P-1 ionic states. Our results confirm the recent experimental prediction that beta for s subshell photoionization in open-shell atoms, is, in general, term and photon energy dependent and, in addition, in the case of chlorine 3s photoionization, beta has minima for both terms of Cl+ 3s(P-3, P-1), in qualitative agreement with experiment. However, our calculation of beta for Cl+ 3s(P-3, P-1) channels demonstrates that interchannel coupling should be included in order to achieve quantitative agreement with experiment.
