Title: vh[sub 11/2] bands in [sup 113]Pd and [sup 115]Pd

Abstract

Two cascades of [gamma] rays were discovered in [sup 113]Pd and [sup 115]Pd in prompt [gamma]-ray spectroscopy with Gammasphere following heavy-ion induced fission in the reaction [sup 18]O+[sup 208]Pb at 91 MeV. Comparison with recently observed band structures in [sup 109]Pd and [sup 111]Pd as well as blocking arguments lead to an interpretation of these bands as [nu]h[sub 11/2] bands. This discovery, together with cranked Woods-Saxon and total Routhian surface calculations, indicates that increased rotational frequency stabilizes a prolate but still [gamma]-soft shape in the neutron-rich, even-even Pd isotopes up to [sup 116]Pd, which exhibit very [gamma]-soft nuclear potentials in their respective ground states.
