E. N. Elekina, A. P. Martynenko

摘要:

在QED束缚态问题的准势方法的基础上,计算了μ子$^3_2He$离子中能级$2P_{1/2}$和$2P_{3/2}$的$α^5$和$α^6$级对精细结构区间$ΔE^{fs}=E(2P_{3/2})-E(2P_{1/2})$和超精细结构的真空极化、相对论、反冲和结构修正.所得值$ΔE^{fs}= 144803.15 μeV$、$Δ\tilde E^{hfs}(2P_{1/2})=-58712.90 μeV$、$Δ\tilde E^{hfs}(2P_{3/2})=-24290.69 μeV$为与相关实验数据进行比较提供了可靠的指导。

英文摘要:

On the basis of quasipotential approach to the bound state problem in QED we calculate the vacuum polarization, relativistic, recoil, structure corrections of orders $α^5$ and $α^6$ to the fine structure interval $ΔE^{fs}=E(2P_{3/2})-E(2P_{1/2})$ and to the hyperfine structure of the energy levels $2P_{1/2}$ and $2P_{3/2}$ in muonic $^3_2He$ ion. The resulting values $ΔE^{fs}= 144803.15 μeV$, $Δ\tilde E^{hfs}(2P_{1/2})=-58712.90 μeV$, $Δ\tilde E^{hfs}(2P_{3/2})=-24290.69 μeV$ provide reliable guidelines in performing a comparison with the relevant experimental data.
