Abstract
Nuclear structure of the neutron‐rich Se, and Ge isotopes is theoretically studied in terms of the spherical full shell model with the monopole and quadrupole pairing plus quadrupole‐quadrupole interaction. The experimental energy levels of low‐lying states as well as high‐spin states are well reproduced. The shell model results are examined in details in a pair‐truncated shell model. The analysis shows the alignment of two g9/2 neutrons at high spins.
