Abstract
Excited states in the extremely neutron-deficient nucleus Te-107 have been identified from two separate experiments using the recoil-decay tagging technique. Two connected structures were observed on the basis of gamma gamma-coincidence relations and tentatively assigned as built on the mixed-parentage nu g(7/2)d(5/2) and nu h(11/2) intruder configurations. The observed structures were compared with large-scale shell-model calculations and total Routhian surface calculations. Collective behavior was discovered to persist in the nu h(11/2) band of Te-107 which highlights the shape-polarizing effect of a single valence neutron occupying the h(11/2) intruder orbit as the N = 50 shell closure is approached.
