103 Nb 的 8 个低位水平的半衰期已在裂变产物分离器 JOSEF 中测定。使用B-γ-γ三重符合方法，该方法包括分别用塑料、BaF2和Ge探测器测量通过103Zr的B-衰变和它们的γ衰变供给能级之间的时间延迟，与标记γ射线一致。大多数研究的能级都是基于基态以及 164 和 248 keV 能级的三个已知旋转带的成员。从半衰期数据可以推导出103Nb的形变Bq=0.31(3)。通过尼尔森模型框架中的计算可以很好地再现半衰期。
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.
