Measurements and predictions of the 6s6p1,3P1 lifetimes in the Hg isoelectronic sequence -: art. no. 042502

Experimental and theoretical values for the lifetimes of the 6s6p(1)P(1) and P-3(1) levels in the Hg isoelectronic sequence are examined in the context of a data-based isoelectronic systematization. New beam-foil measurements for lifetimes in Pb III and Bi IV are reported and included in a critical evaluation of the available database. These results are combined with ab initio theoretical calculations and linearizing parametrizations to make predictive extrapolations for ions with 84 less than or equal toZ less than or equal to 92.
