Theoretical Study of Interesting Fine-Structure Splittings for 23P0, 1, 2 States along Helium Isoelectronic Sequence
-
Abstract
Using the multi-configuration Dirac--Fock method including the Breit interactions and QED corrections, we calculate the fine-structure energy levels of the 23P0, 1, 2 states along the helium isoelectronic sequence with atomic number up to Z=36, where LS-coupling is appropriate. Our calculation results agree with the experimental results within about 1%. We elucidate the mechanism of the interesting fine-structure splittings for the 23P0, 1, 2 states along the helium isoelectronic sequence, i.e. the competitions between the spin--orbit interactions and the Breit interactions which represent the relativistic retardation effect of electromagnetic interactions.
