EFFECTS OF FLUCTUATION OF FREE ELECTRONS ON PHOTOIONIZATION CROSS-SECTION NEAR THRESHOLD
自由电子涨落对光电截面阈值的影响

Based on relativistic HFS self-consistent field average atomic model, the effect of the fluctuation of free electrons on the threshold of photoionization in local thermal equilibrium plasmas is studied by employing the principle of entropy in grand-canonical ensemble. Some results are discussed.
