Abstract

Fine structure in the α decay of high-spin states in ¹⁵⁶Lu and ¹⁵⁸Ta has been identified by means of αγ-coincidence analysis. One new α decay from ¹⁵⁶Lu and two from ¹⁵⁸Ta were identified, one of which was found to populate a previously unknown state in ¹⁵⁴Lu. The hindrance-factor systematics from all four odd-odd, N = 85 nuclei with known α-decaying, πh_11/2 coupled states were reviewed and are discussed. These proved consistent with the previously assigned (πh_11/2νh_9/2) 10⁺ configuration of the α-decaying state in ¹⁵⁶Lu, which differs from the
(πh_11/2νf_7/2) 9⁺ assignments in the other three nuclei.
