“…4 Fig. 2, the yrast 43/2 and 51/2 states lie unusually low and have previously been interpreted as favored yrast noncollective oblate states [8]. The 43/2 state, which has been systematically observed in the light iodine 2 1 isotopes, is built on the 7r (g7/2d5/2) + (hii/2) / 8 v (g7/2)p+ (d5/2)p+ (/111/2) ip+ configuration in I.…”

“…The final energetically unfavored terminating states reside well above yrast. This behavior is to be contrasted with the abrupt favored termination seen in several neighboring nuclei in this mass region, e. g. , the 43/2 and 51/2 yrast states in this nucleus [8] and similar states in odd-A r~r~2~I [9 -13].…”

Multiple band structures at high angular momentum inI115: Towards unfavored band termination

Six new rotational bands have been established in I at high spin using the near symmetric Ni( Ni, 3py) reaction at 250 MeV. Several of the bands are observed to frequencies beyond ho=1.0 MeV (spin approaching 505). All the bands show a characteristic drop oK in their dynamic moments of inertia with increasing spin. The low values at the highest spins are consistent with predictions for a band termination in which a gradual shape change from collective prolate to noncollective oblate occurs over many transitions.These smoothly occurring terminations contrast with the abrupt "favored" terminations previously observed in this and other odd-A iodine nuclei.PACS number(s): 21.10.

Abstract. Applying delayed V-r.f. coincidences and generalized centroid-shift analysis, nanosecond isomers in some odd-A iodine isotopes are studied in-beam. The reactions 1~p2n) and 116'1188n(6Li, 3n) have been 123'125I [10] where the lifetimes of the 11/2~-and 9/2 + band heads were determined. One aim of the present work was to extend the systematics with experimental data for lowlying noncollective states in 115,119,1211.The coexistence of excited states with different shapes which has been observed in the odd-A iodine isotopes gives the opportunity to investigate the strength of the electromagnetic transitions between them. In this way, the expected hindrance can be experimentally studied. This was a further aim of this paper.

High spin states of 119Te, populated in lJ~ 4n) and 11~ 3n) reactions, have been studied through y-ray spectroscopy. The level scheme has been established up to J~ = (55/2-). Three-quasiparticle states, based on :rgZ/z@vhaa/2 and 7zgT/zd5/2@vh11/2 configurations, have been identified. A particularly favoured 39/2-state is suggested to be the fully aligned 2 3 [7~g7/216 + @ [vhl 1/2127/2 -yrast non-collective oblate configuration. This assignment is supported by Total Routhian Surface (TRS) calculations which also suggest a similar oblate assignment to states at 21/2-, 23/2and 37/2-.
