在WBEPM理论下Eu I原子里德堡能级计算

摘要

In this paper,the Rydberg energy levels of 4f7 6snd 6D9/2(n≥13)、4f7 6snd 8D9/2(n≥17)、4f7 6snd 8D5/2(n≥15)and 4f7 6snd 8D3/2(n≥21)for EuI 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 1.91 cm-1.The extrapolated data are credible.%依据最弱受约束电子势模型理论,计算了铕原子4f7 6snd 6D9/2(n≥13)、4f7 6snd 8D9/2(n≥17)、4f7 6snd 8D5/2(n≥15)和4f7 6snd 8D3/2(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1.91 cm-1,达到了较高精度,这表明文中的外推数据是可信的.
