在WBEPM理论下EuⅠ原子里德堡能级计算(英文)

Calculation of Rydberg energy levels for EuⅠ atoms under the WBEPM theory

依据最弱受约束电子势模型理论,计算了铕原子4f76snd6D9/2(n≥13)、4f76snd8D9/2(n≥17)、4f76snd8D5/2(n≥15)和4f76snd8D3/2(n≥21)里德堡系列能级.计算结果与实验值的最大相对误差为4×10-5,最大绝对误差是1.91cm-1,达到了较高精度,这表明文中的外推数据是可信的.

In this paper, the Rydberg energy levels of 4f^76 snd ^6D9/2（n≥13）、4f^76snd^8D9/2（n≥17）、4f^76snd^8D5/2（n≥15）and 4f^76snd^8D3/2（n≥21） for Eu I atom are calculated based on the weakest bound electron potential model theory method, The maximum relative error between the calculated and measured values is 4×10-5 and the maximum absolute error is 1.91cm^-1. The extrapolated data are credible.
