摘要： Many-body perturbation theory with an effective operator is applied to the calculations of photoionization of sodium by consistently including the static and dynamic core polarization. The cross section for the transition (2p→kd+ ks) is obtained by taking into account the dipole and quadrupole core polarization. The results are compared with the many-body perturbation results and measurements.
