Decay spectroscopy of Os 171,172 and Ir 171,172,174
We report on a study of the α-decay fine structure and the associated Eα-Eγ correlations in the decays of Os171,172 and Ir171,172,174. In total, 13 new α-decay energy lines have been resolved, and three new γ-ray transitions have been observed following the new decay branches to Re168 and W167. The weak α-decay branch from the bandhead of the νi13/2 band in Os171 observed in this work highlights a
