Viktor Yakhontov, Klaus Jungmann

摘要:

本文给出了在弱激光场作用下氢原子系统ns态光移的计算结果。这是通过相应水平的标量动态极化率(DP)的分析计算。与通常的技术相比,1.e。通过求解某个非齐次微分方程结果,我们得到了DP的一个封闭的解析表达式适用于所有的主量子数,n。在这种方法的框架下,我们成功地恢复了已知的结果,并发现了几个新的结果,我们的兴趣主要集中在低n态,n= 1,2,因为它们是特别重要的,我们详细讨论了这些能级的DP的各种分析性质。计算了μ原子1 S-2S实验研究中所用激光场的能量和强度的光移数值。

英文摘要:

We present the results of the light-shift calculations in the ns-states of hydrogenicsystems in the presence of a weak laser field. This is done by means of analytical calculations of the scalar dynamic polarizabilities (DP) of the corresponding levels. In contrast to the usual technique, 1.e. by solving certain inhomogeneous differential equation. As a result, we obtained for the DP a closed analytical expression valid for all principal quantum numbers, n. Within a framework of such an approach we succeeded both in retrieving the well known results and finding several new ones, as well.Our interest is focused mainly on the states with low n, n=1,2, since they are of particular importance.Various analytical properties of the DP of such levels are discussed in full details. Numerical values of light-shifts are computed for those energies and intensities of the laser field that are used in the 1S-2S experimental investigation of the muonium atom.
