主 题:angular distribution photoionization many-body perturbation.
摘 要:The differential cross sections and angular distribution parameter of the photoionization processes 2p^63s→2p^53skl of atomic Na have been calculated by using many-body perturbation theory. In the calculation, the resonant structure of the excitation process 2s→3p has been included. The electron correlation interaction was analyzed by using the effective diagram method. The summation of specific classes of these diagrams is to an infinite order. The results of calculations are compared with experimental data, which are in good agreement with the experiment.
