摘要：
Using beam-foil spectroscopy and comparing prompt spectra (recorded close to the foil) with delayed ones we have observed the n = 4, DELTA-n = 0 spin-forbidden transitions 4s2 1S0-4s4p 3P1o in Zn-like Nb XII, 4s(2)4p 2P(o)-4s4p2 4P in Ga-like Nb XI and 4s(2)4p2 3P-4s4p3 5S(o) in Ge-like Nb X. Lifetime measurements support the spectroscopic assignments. The experimental transition probabilities for the 4s2 1S0-4s4p 3P1(0) intersystem line in the Zn I sequence are compared with the rather differenct results of various theoretical calculations.
