The photoionization cross section for the excited Na 4d state has been calculated with the multiconfiguration Hartree-Fock method. Ab initio methods are used to take into account the core-polarization effects. The minimum (zero) in the 4d..-->..kp cross section has been calculated and it is found that including the effects of core-polarization shifts the position of the minimum (zero) to a higher energy. The calculation of the photoionization angular distribution asymmetry parameter is an excellent test to locate the minimum (zero) in the cross section. The present results are in good agreement with the experimental results of Smith et al. (Phys. Rev. A 22, 577 (1980)) performed at a single photon energy.
