Abstract
It was shown that the evolution of the values in = 80 isotones from Te to Nd is affected by the underlying subshell structure. This manifests itself in the observation of the local suppression of the value at with respect to the neighboring nuclei and . To investigate this shell sensitivity toward the subshell gap, the value of the unstable nucleus was measured utilizing the projectile Coulomb excitation technique. The radioactive ion beam (RIB) experiment was performed at the REX-ISOLDE facility at CERN. The value of reflects the impact of the subshell closure at with respect to a linear scaling of collectivity with valence proton number.
