Abstract
The and reduced proton transition probabilities in have been determined from the direct half-life measurements of the and states using the Romanian array for -ray SPectroscopy in HEavy ion REactions (RoSPHERE). The and states were found to have ns and ns respectively. Angular distribution measurements were used to determine an mixing ratio of for the 1609 keV -ray transition deexciting the state. This value for was combined with the measured half-life to give reduced transition probabilities of and . These values are in good agreement with calculations within the finite Fermi system. The extracted value of can be explained by a small () admixture in the wave function of the state.
