ABSTRACT

High spin states of nuclei in the vicinity of neutron shell closure N =82 and proton shell closure Z =82 have been studied using the Clovere Ge detectors of Indian National Gamma Array. The shape driving effects of proton and neutron unique parity intruder orbitals for the structure of nuclei around the above shell closures have been investigated using light and heavy ion beams. Lifetime measurements of excited states in 139Pr have been done using pulsed-beam-γ coincidence technique. The prompt spectroscopy of 207Rn has been extended beyond the 181μs 13/2+ isomer. Neutron-rich nuclei around 132Sn have been produced from proton induced fission of 235U and lifetime measurement of low-lying states of odd-odd 132I have been performed from offline decay.
