The quadrupole moments of some even–even nuclei around the mass of A ~ 80: 68−80 Ge on the neighborhood of 76−84 Kr and 76−84 Se isotopes

We have carried out the calculation of the quadrupole moments Q (2 1 + ) and electromagnetic transition rates B ( E 2) of some levels within the framework of the interacting boson model for even-mass Ge nuclei. The presented predictions of the quadrupole moments and B ( E 2) ratios for Ge nuclei are compared with the results of some previous experimental and theoretical ones along with those of the neighboring Kr and Se isotopes and then it was seen that they agree well with the previous experimental and theoretical ones.
