“…The presence of an isomeric state (8 − , T 1/2 = 83.6 ± 1.7 min) at 120 keV excitation was also reported in Ref. [39,41], it was populated in α-induced fission reaction. No information of the high spin states above this long lived (8 − ) isomer was available.…”

Excited states of neutron rich Iodine isotopes 130−134 I above the high spin isomers have been identified using prompt-delayed γ-ray spectroscopy. The Iodine isotopes have been produced as fission fragments of fusion-fission and transfer induced fission of 9 Be(238 U, f) at a beam energy of 6.2 MeV/u. The complete (A, Z) identification was obtained using the large acceptance magnetic spectrometer VAMOS++. The AGATA γ-ray tracking array was used to detect the prompt γ rays while the delayed γ rays (in the time range of 100 ns to 200 µs) from the isomeric states were identified by the EXOGAM segmented Clover detectors, placed behind the focal plane of VAMOS++ spectrometer. The high spin states above the (8 −) isomers in 130,132 I have been populated for the first time and a new isomer in 132 I has been identified. New γ-ray transition has also been assigned to the level structure of 134 I. Prompt transitions above the 19/2 − isomer have been identified in 131,133 I, for the first time. The level structures are interpreted in terms of the systematics of odd-Z nuclei above Z = 50 shell closure and large scale shell model calculations.

“…In this β-decay study, only the low spin states were popu- lated. The lifetime and magnetic moment measurements of low spin states have been reported in various investigations [40][41][42]. The presence of an isomeric state (8 − , T 1/2 = 83.6 ± 1.7 min) at 120 keV excitation was also reported in Ref.…”

We have done the microscopic study of neutron-rich odd-odd iodine isotopes within the framework of projected shell model. Odd-odd nuclei are the best candidates for studying possible structure variations away from the valley of stability. We used the projected shell model, in which the deformed Nilsson single-particle states are being used for the construction of model basis. We studied the band properties of odd-odd I[Formula: see text](Z [Formula: see text] 53) isotopes with neutron numbers N [Formula: see text] 75, 77, 79, 81, 83 and 85. Using model analysis, we presented the low-lying positive- and negative-parity states of these nuclei. In these isotopes, the band structures have been analyzed in terms of quasi-particle configurations and comparative presentation of yrast levels is discussed. The phenomenon of yrast energy splitting is also studied in this work.
