Abstract

The B(E2; 0₁⁺ → 2₁⁺) values for the radioactive neutron-rich germanium isotopes ^78,80Ge and the closed neutron shell nucleus ⁸²Ge were measured at the HRIBF using Coulomb excitation in inverse kinematics. These data allow a study of the systematic trend between the subshell closures at N = 40 and 50. The B(E2) behavior approaching N = 50 is similar to the trend observed for heavier isotopic chains. A comparison of the experimental results with a shell model calculation demonstrates persistence of the N = 50 shell gap and a strong sensitivity of the B(E2) values to the effective interaction.
