低密度Fe、Ni等离子体电子温度的研究

Study of Electron Temperature for Low-density Plasma

对于低密度等离子体 ,计算了铁 (Fe)、镍 (Ni)两种等离子体的伴线j(1s2 2p2 P3 / 2 - 1s2p2 2 D5/ 2 )与共振线w(1s2 1S0 - 1s2p1P1)相对强度随温度变化关系 ,根据此关系从理论上得到电子温度 ,为实验诊断电子温度提供了有益的参考。计算时 ,对共振线w进行了修正 ,这些修正分别来自未分辨伴线对w的贡献、类锂离子电离及类氢离子复合对w的影响 ,比较精确地计算出共振线w的强度。同时用Hartree Fork Relativistic (HFR)方法计算了伴线因子和波长 。

For low density plasmas,the intensity ratio of satellite line j to resonance line w for He like Fe、Ni plasmas is calculated,and the results give a useful reference for temperature diagnostics. The contributions of unresolved satellite lines to resonance line were considered, as well as the contributions from recombination of H like ions and ionization of Li like ions. The satellite line factors of He like Fe、Ni plasmas have been calculated using HFR method, and satellite line intensity was obtained.
