摘要:

使用Dirac-Fock模型计算了周期表中几个$Z$值下K个$β$超卫星谱线的能量和跃迁概率。计算了Breit相互作用对相应谱线的能量位移和K $β\_{1}^{\rm h}$ /K $β\_{3}^{\rm h}$强度比的影响。计算了Al和Sc的双K空穴能级的宽度,并与实验和其它理论计算结果进行了比较。

英文摘要:

Energies and transition probabilities of K$β$ hypersatellite lines are computed using the Dirac-Fock model for several values of $Z$ throughout the periodic table. The influence of the Breit interaction on the energy shifts from the corresponding diagram lines and on the K$β\_{1}^{\rm h}$/K$β\_{3}^{\rm h}$ intensity ratio is evaluated. The widths of the double-K hole levels are calculated for Al and Sc. The results are compared to experiment and to other theoretical calculations.
