论文摘要
Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions, we perform a detailed study of electric dipole (E1) transition amplitudes in K, Ca+, Rb, Sr+, Cs, Ba+, Fr, and Ra+, which are of interest for studies of atomic parity violation, electric dipole moments, and polarizabilities.使用全端子相关潜在方法，我们对低延lying s，p和d状态之间的E1过渡幅度进行高精度计算。我们执行鲁棒的误差分析，并将计算与许多幅度进行高精度实验确定的幅度进行比较。我们发现非常同意，偏差的水平约为0.1％。我们还将结果与其他理论评估进行了比较，并讨论了对不确定性分析的含义。此外，将分支比的计算与最近的测量相结合，我们提取了CA+，SR+，CS，FR和RA+的几个E1振幅的高精度值。
Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions, we perform a detailed study of electric dipole (E1) transition amplitudes in K, Ca+, Rb, Sr+, Cs, Ba+, Fr, and Ra+, which are of interest for studies of atomic parity violation, electric dipole moments, and polarizabilities. Using the all-orders correlation potential method, we perform high-precision calculations of E1 transition amplitudes between low-lying s, p, and d states. We perform a robust error analysis, and compare our calculations to many amplitudes for which there are high-precision experimental determinations. We find excellent agreement, with deviations at the level of ~0.1%. We also compare our results to other theoretical evaluations, and discuss the implications for uncertainty analyses. Further, combining calculations of branching ratios with recent measurements, we extract high-precision values for several E1 amplitudes of Ca+, Sr+, Cs, Fr, and Ra+.
