Hindered El Transitions in Eu{sup 155} and Tb{sup 161}

Abstract

The absolute E1 transition probabilities from the 3/2{sup +} (411), 5/2{sup -} (532) and 7/2{sup -} (523) single particle levels in Eu{sup 155} and Tb{sup 161} have been measured by the method of delayed coincidences. This gave half lives of T{sub 1/2} < 0.2 ns and T{sub 1/2} = (1.38 {+-} 0.06) ns for the 104.4 and 246 keV levels in Eu{sup 155}. T{sub 1/2} = (0.84 {+-} 0.04) ns and T{sub 1/2} < 0. 2 ns for the 417.6 and 480.6 keV levels in Tb{sup 161}. The result has been compared with the calculations of a single particle in a deformed potential made by Nilsson.
