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: T_{1 2}(3⁺, 381.2 keV) = 2.3(2), ns, T_{1 2}(1^-, 192.9 keV) = 0.7(2) ns, T_{1 2}(1^-, 247.6 keV) = 0.4(1) ns, T_{1 2}(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.
