摘要 利用多通道量子亏损理论(MQDT)分析了铅原子奇宇称6pnd J=2 Rydberg系列能级,计算出6pnd(6≤ n ≤ 63)J=2 Rydberg系列能级的能量位置,得到了最优化的MQDT参数。利用这些参数计算了每个能级的通道混合系数,并根据混合系数确定了每个能级的原子态符号。计算结果表明,在所研究的能量范围内,6p6d(3/2)[5/2]_2~0和6p6d(3/2)[3/2]_2~0两个干扰态附近的能级出现强烈的通道混合现象。采用与文献中不同的五通道计算模型,确定了其他文献中没有报道的铅原子的21个6pnd(1/2)[3/2]_2~0能级的位置,并确定了铅原子能量在59788cm^(-1)以下的所有奇宇称6pnd J=2 Rydberg态的能级符号,计算结果清楚地显示出各通道间的通道混合和相互作用情况。
