Abstract
Fine structure in the α decay of high-spin isomers in Lu155(25/2−) and Hf156(8+) has been studied for the first time using αγ-coincidence analysis. Three new α decays from Lu155(25/2−) and two from Hf156(8+) have been identified, populating seniority s>1 states in the N=82 nuclei Tm151 and Yb152, respectively. The reduced hindrance factors of the α decays support the previous configuration assignments of the populated states. This is the first observation of states with excitation energy greater than 1.5 MeV being populated following α decay in nuclei outside of the Pb208 region.
