Structure of 108Ag at low and medium spin

Study of band structures of nuclei from symmetry consideration plays an important role in understanding different phenomena in nuclear structure. In selected regions of the nuclear landscape, axial symmetry is broken and these nuclei, referred to as transitional nuclei, are described using the triaxial deformed mean-field. There are several empirical observations indicating that axial symmetry is broken in transitional regions. The structure of the gamma vibrational bands and their decay provide information about the nature of triaxial shapes. In addition, the chiral rotation is uniquely related to the triaxial nuclear shapes. Recently, RMF calculations predict multiple chiral bands in some of the odd-odd isotopes of Ag, Rh and In owing to their triaxial shape. However, in our recent work, the lifetime measurements of the excited states of 112In along with the Tilted Axis Cranking calculations suggest small axially symmetric deformation for this nucleus at lower excitation energy in contradiction to the predictions of RMF calculations. As a part of this investigation to look for multiple chiral bands, the detailed spectroscopy of 108Ag was carried out up to medium spin in the present work. The present measurement also aims to look at the low-lying states near the isomer with energy 111 keV and T1/2 = 418 years to understand and estimate the induced depletion of this long-lived isomer
