钽激光等离子体的自电离和辐射衰减特性(英文)

在自旋轨道劈裂阵模型下,考虑组态间的耦合,计算出类铜钽激光等离子体的跃迁组态的波长和对应的波数,通过组态平均分析了其自电离与辐射跃迁特性,得出相关的自电离系数和辐射衰减系数,这些参数为分析高离化钽激光等离子体的双电子复合过程提供了重要的理论依据.

The autoionization and radiative-transition probabilities in laser-produced tantalum plasmas

The autoionization and radiative-transition probabilities are computed in the form of averages for whole configurations or subconfigurations of Cu-like tantalum.The compact formulas for these averages are valid in intermediate coupling,avoiding any diagonalization.For the transition subarrays suspected to be responsible for the pseudocontinuum,the average wavelengths are computed in the formalism of spin-orbit-split arrays.These parameters will provide a theory proof for analyzing dielectronic recombination process of highly ionized tantalum.
