摘要:

比较了计算氢原子高激发态双光子衰变率的相对论和非相对论方法。研究了ns、nd和np初始态对主量子数(n)的依赖关系,当n = 100时,非共振发射的主量子数为100。对于ns态以及主E1E1通道,考虑了较高多极子(M1M1,E2E2,E1M2)的贡献。对于np状态,评估E1M1和E1E2通道。在非相对论极限下,导出了E_1M_1衰变的简单解析公式。

英文摘要:

The relativistic and nonrelativistic approaches for the calculations of the two-photon decay rates of highly excited states in hydrogen are compared. The dependence on the principal quantum number (n) of the ns, nd, and np initial states is investigated up to n = 100 for the nonresonant emissions. For the ns states together with the main E1E1 channel the contributions of higher multipoles (M1M1, E2E2, E1M2) are considered. For the np states the E1M1 and E1E2 channels are evaluated. Moreover, the simple analytical formula for the E1M1 decay is derived in the nonrelativistic limit.
