Study of strongly coupled bands in 113Sb

The low lying states in antimony isotopes (Z = 51) are single particle in nature. These states arise due to the coupling of valance proton g7/2, d5/2 and h11/2 orbitals to the spherical Sn (Z = 50) core. Collective states in these antimony isotopes are thought to arise from the excitation of g9/2 proton across the Z = 50 shell gap leading to two particle-one hole (2p-1h) excitations based on the (g7/2)2 x (g9/2)-1 configuration. Two such sequences of ΔI = 1 bands have been reported. Furthermore, many decoupled ΔI = 2 rotational-like deformed bands have been recently identified up to high-spin states in different Sb isotopes. These states have been interpreted to arises due to the coupling between the valence nucleons occupying the h11/2, g7/2, and d5/2 orbitals and the 2p-2h deformed core states of Sn. The present work concerns the study of two strongly coupled bands in 113Sb
