Collective and noncollective states in 116Sb

Excited states of Sb-116 were investigated using in-beam gamma-ray spectroscopy techniques with the Cd-114(Li-7, 5n) reaction. About 25 new states and 35 new transitions were added into the level scheme of Sb-116. The previously known two rotational bands based on the pi g(9/2)(-1) circle times nu h(11/2) and pi g(9/2)(-1) circle times nu d(5/2) configurations have been extended up to (16)(-) and (13)(+) states, respectively. A new Delta I = 1 band was identified, and interpreted in terms of the triaxial particle rotor model calculations.
