利用单通道松弛轨道hartri - fock近似计算了Na原子在基态和激发态2p6nl （n = 3,4,5和l≤n - 1）下的2p电子单光子电离、震荡和震荡过程的截面和不对称参数β。计算出的截面对价电子的原子轨道有很强的依赖性。不对称参数β对价电子在光电离阈值附近的激发很敏感。发现Na原子在4d、2D、5p2p和5f2f态的2p亚壳层单次光离的可能性分别比振荡过程小约43、150和105倍。
The cross sections and asymmetry parameters β of the 2p electron single photoionization, shake-up and shake-down processes from Na atoms in the ground state and in a number of excited states 2p6nl (n = 3, 4, 5 and l ≤ n–1) are calculated using a single channel relaxed-orbital Hartree–Fock approximation. A strong dependence of the calculated cross sections on the atomic orbit of the valence electron is found. The asymmetry parameters β are sensitive to the excitation of the valence electron near the threshold of photoionization. The single photoionization of the 2p subshell of Na atoms in the 4d 2D, 5p 2P and 5f 2F states is found to be about 43, 150 and 105 times less probable respectively than the shake-up process.
