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, πh11/2 coupled states were reviewed and are discussed. These proved consistent
with the previously assigned (πh11/2νh9/2 )10+ configuration of the α-decaying state in 156Lu, which differs from
the (πh11/2ν f7/2 )9+ assignments in the other three nuclei.

Impact of the surface energy coefficient on the deformation properties of atomic nuclei as predicted by Skyrme energy density functionals
Ryssens, W.; Bender, M.; Bennaceur, Karim; Heenen, P.-H.; Meyer, J. (American Physical Society, 2019)Background: In the framework of nuclear energy density functional (EDF) methods, many nuclear phenomena are related to the deformation of intrinsic states. Their accurate modeling relies on the correct description of the ... -
