Abstract
The mean lives of the lowest 9(-) and 12(+) states of Sm-146 have been meas ured by means of the RDM. Their (preliminary) values are tau(m)(9(-)) = 0.9 7 +/- 0.05 ns and tau(m)(12(+)) = 15 +/- 2 ps, respectively The strengths o f the collective E3 transitions of the 12(+) --> 9(-) --> 6(+) cascade are compared with the corresponding ones in Gd-148.
