Investigation of isomers around mass 200 region

Investigation of isomers in nuclei near shell closures is important to understand the active configurations of single particle orbitals, which are further treated as essential ingredients of model calculations. Several isomers have been reported in nuclei near Z = 82 in mass 190-200 region. Spin isomers originating from the yrast traps are common in those nuclei which are spherical or weakly deformed. The presence of isomers in Au, Tl, Hg isotopes populated in above reaction, using the time stamped gamma-gamma coincidence data obtained with digital data acquisition system has been investigated
