Collective and noncollective states in Te-117

High-spin states of the Te-117 nucleus were studied by in-beam gamma-ray sp ectroscopy with the Rh-103(O-18,p3n) fusion-evaporation reaction at a beam energy of 85 MeV. gamma-gamma coincidence and gamma-gamma angular correlati on analyses were employed for determining the level scheme of Te-117. The p reviously known states based on the nu h(11/2) orbital have been widely ext ended and some states have been corrected. Based on the TRS calculations, m any unusually low-lying states in their excitation energies have been assig ned to noncollective oblate states built on various quasiparticle configura tions with beta(2) approximate to 0.17 and gamma = 60 degrees. Meanwhile, i n the positive-parity states built on the nu g(7/2)[413]5/2(+) and the nu d (5/2)[402]5/2(+) configurations, the vibrational- and the rotational struct ures have been found to coexist.
