Band structures in 116 Sb

The study of odd-odd nuclei around Z = 50 shell closure is interesting to study the collective as well as the single particle states. The odd-odd nuclei exhibit the combined features of odd proton and odd neutron. At low excitation energy, the nuclei around A~100 of this region, are expected to be dominated by the single particle excitations. It has been observed that the nuclei also exhibit collective structures that coexist with the single particle structures. With energy and angular momentum the collectivity develops, through the occupation of h11/2 high-j negative parity orbital and also through the promotion of a proton from g9/2 -upsloping orbital into the -downsloping g7/2 orbital and thereby, leads the system towards the prolate deformation. The Sb isotopes, near Z = 50 magic shell closure, can provide an ideal laboratory for exploring the single as well as the collective structures within a single nuclear system. So far the information available on the structure of 116 Sb [1-3] is not enough compared to its neighboring isotopes. The aim of present work is to look for the near yrast structures of 116 Sb populated via -beam and to look for the crossover E2 transitions for the previously predicted magnetic rotational band [3].
