High-spin bands have been established in I-111(53) and Xe-113,114(54) that
show the characteristics of smooth termination. Unlike the majority of such
bands in Z approximate to 50 nuclei, which contain particle-hole excitatio
ns across the spherical Z = 50 shell gap, the new bands appear to be built
on less-deformed valence-space configurations. This is supported by lifetim
e measurements in Xe-114.
