Abstract

Excited states of $^{156} Dy$ were populated through $β^{+} / ɛ$ decay and studied through γ-ray spectroscopy at the Yale Moving Tape Collector. Extensive data led to improved information on the electromagnetic decay properties of low-spin states and to a substantially revised level scheme. The structural observables of $^{156} Dy$ are compared with those of the other nearby $N = 90$ isotones and to predictions of the $X (5)$ model for nuclei in the spherical-deformed transition region.
