摘要 利用多通道量子亏损理论(MQDT),对锡原子奇宇称5pnd和5Pns组态的J=1,2简并受扰Rydberg系列能级进行了理论分析研究.通过拟合实验能级,得到了MQDT优化参数,所得理论能级值与文献报道的实验结果符合得很好.由算得的通道混合系数,分析讨论了通道相互作用特性,确定了所有能级的原子态命名.本文结果有助于人们更好地了解锡原子高激发态的能级结构和组态相互作用特性. Energy levels along the odd-parity 5pnp and 5pns J = 1 and 2 Rydberg series of Sn I have been analyzed by multiehannel quantum defect theory (MQDT). A rather good agreement between theoretical and experimental energy levels was achieved. The optimal MQDT parameters which were used to calculate the theoretical energy levels and admixture coefficients for all of these levels were obtained. Based on the calculated admixture coefficients of each channel, interchannel interactions were discussed in detail and assignments of all the levels were determined. The results are helpful to understand the characteristics of configuration interaction among odd-parity levels in Sn I.
