Collective Structures in 116 Sb

The excited states of 116 Sb have been studied using in-beam γ -spectroscopy techniques with 115 In( α , 3n) ^116 Sb reaction and Indian National Gamma Array (INGA) setup at VECC, Kolkata. Various collective structures have been populated in the α -induced fusion evaporation reaction. Two of the previously known bands based on ( πg_9/2^ - 1⊗νd_7/2^1 ) and ( πg_9/2^ - 1⊗νd_5/2^1 ) configurations are extended to (14 + ) and 16 + spin, respectively and also pair-breaking has been reported in the later. Crossover E2 transitions could also be identified in one of the bands reported earlier.
