Abstract
Many-body perturbation theory with an effective operator is applied to the calculations of photoionization of sodium by consistently includi ng the static and dynamic core polarization. The cross section for the transition (2p --> kd + ks) is obtained by taking into account the di pole and quadrupole core polarization. The results are compared with t he many-body perturbation results and measurements.
