类铍离子(Z=21～92)的M1跃迁的X射线激光光谱的理论研究
Studies on M1 Transitions for Be-like Ions Related to X-ray
摘要
根据全相对论多组态方法,采用GRASP2程序,系统计算了类铍离子等电子序列(Z=21～92)禁戒跃迁(1s22pnd)1(n=3～4)-(1s22p3??Ad-G??)0的能级间隔、自发跃迁系数和加权振子强度.结果表明:高离化度(q≥51)离子激发态禁戒跃迁的跃迁几率与中性原子的电偶极E1的跃迁几率相当.在ICF和MCF高温激光等离子体中,其跃迁过程不容忽视.同时,对在双电子复合机制下实现粒子数反转的X射线激光工作物质进行了初步探讨.
Abstract
The energy intervals, spontaneous transition possibilities and oscillator strengths of forbidden transitions for Be like ions (Z=21～92) have been calculated by relativistic many configurations method with Breit correction, QED correction and nuclear effective volume correction. In addition, Be like ions as a laser media with population reversion by combination mechanism has been discussed.
