摘要: High spin states in 127I were populated via 124Sn(7Li, 4nγ) fusion-evaporation reaction with Ebeam = 33 MeV. Level scheme of has been updated by placing new γ-rays and also confirming the spin/parity several energy levels. Two levels at Ex 2628 3199 keV have identified which are found to decay negative parity πh11/2 band. These two earlier reported 3502 3989 interpreted as γ-vibrational on basis their pattern. positive three-quasiparticle bands above Iπ 23/2+ 2901 3060 be a possible candidate chiral A comparison isotopic isotonic chains reveals existence γ-vibration rotation 123−127I.
