THE 5DND AND 5DNG J = 4, 3 AND 2 AND 5DNS J = 2 SERIES IN BARIUM - LINEWIDTHS AND LINESTRENGTHS

The 5 dnd and 5 dngJ=2, 3 and 4 as well as the 5 dnsJ=2 autoionising series of barium have been studied with two-step pulsed laser excitations in an atomic beam. Dipole moments and the interactions with the 6 s∈l continua were fitted starting from existing Multi-channel Quantum Defect Theory (MQDT) analyses. The interactions of the 5 dndJ=4 and 2, and 5 dnsJ=2 series with 6 sεgJ=4 and 6 sεdJ=2 continua could be analysed succesfully. © 1989 Springer-Verlag
