摘　　要：使用相对论组态相互作用方法(relativistic configuration interaction,RCI)和细致能级-能级方式计算了类氖氙离子单激发态的能级、类氖氙离子LMM双电子伴线的辐射跃迁能量、辐射衰退几率和强度因子,计算中包含了Breit相互作用、真空极化和自能。对比了氖氙离子LMM双电子伴线与其母线的波长和强度因子,结果表明:双电子伴线与其母线的波长相差不大,强度比对温度的变化很敏感,类氖氙离子LMM双电子伴线强度与母线强度比可应用于氙等离子体温度的诊断。The energy levels of single excited states of neon-like xenon were calculated by using relativistic configuration interaction （ RCI） method.The transition energies, rates and intensity factors of LMM dielectronic satellite lines for ne-on-like xenon were performed with detailed level-by-level mode considering Breit interaction, vacuum polarization and self energy.The wave lengths and intensities between LMM dielectronic satellite lines and parent lines were compared. The results show that the wave lengths between dielectronic satellite lines and parent lines are little difference;the ratio of intensity factors between dielectronic satellite lines and parent lines changes quickly with temperature changing.The ratio of intensity factors between dielectronic satellite lines and parent lines can be applied to diagnosis plasma temperature.
