μ子原子的真空极化:中低Z的Lamb位移

Vacuum polarization in muonic atoms: the Lamb shift at low and medium Z

Savely G. Karshenboim, Vladimir G. Ivanov, Evgeny Yu. Korzinin

摘要:

在μ子原子中,Uehling势(自由电子真空极化回路的效应)对兰姆位移的主要贡献负责,导致状态分裂,其中Delta n = 0和Delta l \neq 0。在这里,我们考虑领先的非相对论近似中的兰姆位移,即,在一个基于薛定谔方程的方法中只要(Z alpha)^2 >> 1,这对低和中$Z$有效。结果是几个参数的函数,包括kappa = Z α m_ mu/m_e,n和l。我们提出了各种渐近性,特别是我们研究了一个区域的渐近性与大,小的卡帕。特别注意的是循环状态,这是考虑在限制n >> 1。

英文摘要:

In muonic atoms the Uehling potential (an effect of a free electronic vacuum polarization loop) is responsible for the leading contribution to the Lamb shift causing the splitting of states with Delta n = 0 and Delta l \neq 0. Here we consider the Lamb shift in the leading nonrelativistic approximation, i.e., within an approach based on a certain Schrodinger equation. That is valid for low and medium $Z$ as long as (Z alpha)^2 >> 1. The result is a function of a few parameters, including kappa = Z alpha m_ mu/m_e, n and l. We present various asymptotics and in particular we study a region of validity of asymptotics with large and small kappa. Special attention is paid to circular states, which are considered in a limit of n >> 1.
