类Be离子Z=8-54内壳层激发态禁戒退激发过程

Forbbiden Decay Processes of Core-Excited States of Be-Like Ions of Z=8-54

采用基于全相对论框架的多组态Dirac-Fock方法,系统研究了类Be离子Z=8-54内壳层激发态1s2P3和1s2s^22p的结构和辐射退激发过程,详细讨论了禁戒跃迁过程随Z的变化.结果表明:对于大部分原子态,禁戒跃迁可以忽略,但对于原子态1s2p^(35)S_2和1s2s^22p ~3P_(0,2),随着Z的增大,禁戒跃迁过程迅速增大,不可忽略.

Forbbiden decay processes of core-excited states 1s2p^3 and 1s^2s22 p of Be-like ions of Z=8-54 are systemly studied using MCDF method.Forbbiden decay rates along with Z are discussed systemly.Results show：for most of the states,forbbiden decay processes can be ignored,but to states 1s2p^3S2and1s^2s^22 p^3P0.2,forbbiden decay rates become bigger along with increasing Z,and it can not be ignored.
