“…At the deformation (6 ~ 0.14) suggested by Lieder et al [2] we expect the 1/2-[301] state at a low excitation energy. Assuming the levels in question to be members of a K= 1/2 rotational band gives an experimental decoupling factor a = -0.14 whereas the Nilsson model predicts a ~ 1 at moderate deformations for a band built on the 1/2-[301] state [11,12]. According to the Nilsson model the only alternative 1/2-states for 28<N<50 are the 1/2-[310] and 1/2-[321] states.…”

“…In order to get the right qp, the two superconducting equations were solved separately for protons and neutrons. Nitsson parameters were taken from [11]. Both pairing strenghts were adjusted so as to reproduce the gaps corresponding to the odd-even mass differences in this region.…”

A model has been investigated describing a situation in which two noninteracting high-j Nilsson-BCS quasiparticles move in the deformed field of an axially and reflection symmetric rotor. According to the positions of the j-shells with respect to the proton and neutron Fermi surfaces structures of different character emerge referred to as semi-and doubly-decoupled. In particular, strongly Coriolis-distorted bands recently reported in doubly odd T1 nuclei are discussed. Also ~h9/2 bands in neighbouring odd mass TI isotopes are analysed on the same footing. It is shown that the pronounced odd even staggering of the transition energies can be understood as a specific quantal feature associated with the Coriolis interaction.

The doubly even isotopes of Zn and Ge have been investigated in a model in which two quasiparticle excitations, constructed in a (0f7/2), lp3/2, Ofs/2, lpl/2,099/2 configuration 4-0 56 space, are coupled with quadrupole vibrations of the core, viz. Ca or Ni. The 0f7/2 orbit is excluded in case of a 56Ni core. The spectra, except for low-lying excited 0 + states, could be reproduced reasonably well. The calculated E2 strengths and quadrupole moments are in fair agreement with experiment.
