| 摘 要： | 利用多组态Dirac Fock(MCDF)理论方法 ,系统地研究了延迟和相关效应对中性XeI原子5p56s[3/ 2 ]2—5p61S0 (M2 )辐射跃迁的影响 ,给出了亚稳态 6s[3/ 2]2的辐射寿命.与最新的磁光阱实验观测结果比较,目前的计算不仅大大提高了理论计算的精度 ,而且解释了实验和以往理论偏差非常大的原因. The recent high precision measurement on the lifetime of metastable 6s state of atomic xenon shows a difference with previous prediction by a factor of 2-3. In the present work, a new theoretical method which can systematically treat relaxation and correlation effects on the basis of the MCDF method is used to study the M2 transitions between the 5p 56s and 5p 6 configurations. By including the correlation contributions of the single and double excitations from the 5l subshells...
