Collective and noncollective states in 117Te

High-spin states of the 117Te nucleus were studied by in-beam γ-ray spectroscopy with the 103Rh(18O, p3n) fusion-evaporation reaction at a beam energy of 85 MeV. γ-γ coincidence and γ-γ angular correlation analyses were employed for determining the level scheme of 117Te. The previously known states based on the νh((11)/(2)) orbital have been widely extended and some states have been corrected. Based on the TRS calculations, many unusually low-lying states in their excitation energies have been assigned to noncollective oblate states built on various quasiparticle configurations with β2 ∼ 0.17 and γ = 60 deg. Meanwhile, in the positive-parity states built on the νg((7)/(2))[413]((5)/(2))+ and the νd((5)/(2))[402]((5)/(2))+ configurations, the vibrational- and the rotational structures have been found to coexist
