Abstract

Proton particle-hole excitations across the Z=50 closed shell are responsible for inducing low-lying prolate deformation in even-50Sn nuclei. Although related rotational bands have been studied in odd-51Sb isotopes involving the coupling of a valence proton, none had been found in odd-50Sn nuclei. Using the Ru96(19F,3pn) reaction, a decoupled band has been observed in Sn111 extending to a spin-parity of (67/2-) and feeding out at 23/2- into spherical states. This band is interpreted as the νh11/2 valence orbital coupled to the deformed [(πg7/2)2(πg9/2)-2] Sn110 core. The extracted band properties are compared to those in Sb111 with the same deformed core.
