lead%Rydberg energy level%multichannel quantum defect theory
Energy levels of the odd-parity 6pnd J = 2 Rydberg states of atomic lead are analyzed by the multichannel quantum defect theory (MQDT) with previous experimental energy levels. The 6pnd (6 ≤n ≤ 63) J = 2 Rydberg energy levels are calculated and optimal MQDT parameters were obtained. Using these parameters, admixture coefficients for each level are calculated to designate the level denotations. The results show that strong channel mixings exist for the levels near the 6p6d (3/2)[5/2]2o and 6p6d (3/2)[3/2]2o pertubers. The five-channel model different from that in literature is used to predict 21 energy positions of 6pnd (1/2)[3/2]2o levels and to determine the denotations of all the 6pnd J = 2 Rydberg states under 59788 cm-1 for Pb I.
