Description
The band structure of the Se and Ge isotopes around the mass 80 is
studied in terms of the full-fledged shell model. The monopole and
quadrupole pairing plus quadrupole-quadrupole interaction is
employed as an effective interaction. As for single-particle levels, all
the four orbitals in the major shell between the magic numbers 28
and 50 are taken into account for both neutrons and protons.
The calculation reproduces the experimental energy levels of
high-spin states as well as low-lying states well. The shell model
results are examined in a pair-truncated shell model, where the full
shell model space is restricted within the subspace of collective pairs.
The results of these calculations will be presented and discussed in
this symposium.
