“…for the transition to the L = 2, J π = 5/2 − α-cluster state at E x = 810 keV. These experimental data [51] confirm that the state at E x = 1500 keV is the L = 4, J π = 9/2 − α-cluster state in 93 Nb = 89 Y ⊗ α. The folding potential has been calculated throughout this work using a simplistic scaling of the radius parameter of the density of the core nucleus with r ∼ A 1/3 .…”

Properties of intermediate mass nuclei have been investigated within the framework of the α-cluster model in combination with systematic double-folding potentials. Previously, this α-cluster model has been widely applied to light nuclei, in particular to 8 Be = α ⊗ α, 20 Ne = 16 O ⊗ α, and 44 Ti = 40 Ca ⊗ α, and to heavy nuclei, in particular to 212 Po = 208 Pb ⊗ α. In the present work a wide range of nuclei is investigated with the magic neutron number N = 50 in the mass range around A ≈ 80 − 100: (A+4,N =52) = (A,N =50) ⊗ α. It is found that excitation energies, decay properties, and transition strengths can be described successfully within this model. The smooth and small variation of the underlying parameters of the α-nucleus potential may be used for extrapolations to predict experimentally unknown properties in the nuclei under study.

“…The systematics of the potential parameters strengthens a reassignment of J π of the state at E x = 1500 keV in 93 Nb. Whereas J π = 7/2 is found in [1], a recent experiment [51] has found strong evidence for J π = 9/2 − and measured a transition strength of 26.4…”

“…The 3 state at E x =0.687 MeV and the 5 state at E x =0.810 MeV are considered to be doublet states, in which the α particle is orbiting around the core with L = 2. Recently Orce et al23 observed a strong E2 transition from the9 state at E x =1.500 MeV to the 5 state (E x =0.810 MeV) with B(E2)=26.4 +9.…”
