Abstract

The half-lives of low-lying levels in 198Au are determined by means of delayed coincidences and generalized controid-shift analysis in the (n, γ) reaction as follows: T12(3+, 381.2 keV) = 2.3(2), ns, T12(1, 192.9 keV) = 0.7(2) ns, T12(1, 247.6 keV) = 0.4(1) ns, T12(4, 215.0 keV) = 0.4(2) ns. In some cases, decompositions of complex distributions were carried out in order to determine the corresponding time centroids. Upper limits are derived for the lifetimes of several other low-lying levels. The deduced electromagnetic transition probabilities B(σL) are compared to results of a new IBFFM calculation.
