Abstract
Tie half-lives of 8 low lying levels of103Nb have been determined at the fission-product separator JOSEF. A B-γ-γ triple-coincidence method was used which consists in a measurement of the time delay between the feeding of the levels through the B− decay of103Zr and their γ decay, in coincidence with a tagging γ ray, with plastic, BaF2 and Ge detectors, respectively. Most of the investigated levels are members of the three known rotational bands based on the ground state and the 164 and 248 keV levels. The deformation Bq=0.31(3) of103Nb could be deduced from the half-life data. The half-lives are well reproduced through calculations in the frame of the Nilsson model.
