Nuclear structure and reaction studies with gamma detector arrays at IUAC

Abstract

Indian national gamma array (INGA) and gamma detector array (GDA) have been the work horse for nuclear structure studies at IUAC. Many of these studies have revealed a variety of modes of excitations in nuclei as a function of spin, iso-spin and excitation energy. These excitation modes mirror different underlying symmetries and structures in nuclei for a given mix of above mentioned quantities. Further, there is a rich inter-play between these various modes or degrees of freedom and it’s a challenge to experimentally identify and theoretically comprehend the rich spectra exhibited. INGA and GDA setups have also been successfully used in recent years for studying reaction dynamics like incomplete fusion and fusion-fission in heavy ion collisions at energies of about few MeV per nucleon.
