摘要/Abstract

摘要： The Schrödinger equation for the $2$S and $2$P states of the lithium-like ions $Z=5$-7, 9-10 is solved by using the Rayleigh-Ritz variational method in Hylleraas coordinates. The leading-order relativistic and QED corrections are calculated perturbatively and higher-order corrections are estimated. The transition frequencies between the $2{\rm S}_{1/2}$ and $2{\rm P}_J$ ($J=1/2, 3/2$) states are determined and compared with experimental and other theoretical results. Specifically, isotope shifts are also calculated for B$^{2+}$.

Abstract: The Schrödinger equation for the $2$S and $2$P states of the lithium-like ions $Z=5$-7, 9-10 is solved by using the Rayleigh-Ritz variational method in Hylleraas coordinates. The leading-order relativistic and QED corrections are calculated perturbatively and higher-order corrections are estimated. The transition frequencies between the $2{\rm S}_{1/2}$ and $2{\rm P}_J$ ($J=1/2, 3/2$) states are determined and compared with experimental and other theoretical results. Specifically, isotope shifts are also calculated for B$^{2+}$.
