The structure of moderately neutron-rich nuclei studied with the CLARA-PRISMA setup and perspectives for the AGATA Demonstrator coupled to PRISMA. — •Andres Gadea — CSIC-Instituto Fisica Corpuscular, Valencia, Spain and INFN-Laboratori Nazionali di Legnaro, Italy

The study of neutron-rich nuclei, in particular large isospin values, is one of the most challenging problems in nuclear structure. Among the open questions is of special interest the evolution of the nuclear effective interactions, in particular of the monopole term, with consequences in the quenching of the known shell gaps and development of new ones. Recently it was developed a new setup at LNL by coupling the CLARA array to the magnetic spectrometer PRISMA This setup aims at measuring in-beam prompt coincidences of gamma-rays detected with CLARA in coincidence with the products of multinucleon-transfer reactions and deep-inelastic collisions, detected by PRISMA. In this contribution we will briefly describe the capabilities of the setup as well as the results obtained for nuclei in the vicinity of 78Ni, populated in the 238U + 82Se at 505 MeV reaction, in the vicinity of 132Sn where the nuclear species had been populated in the 238U + 136Xe at 940 MeV reaction and in the vicinity of 48Ca populated in the 238U and 208Pb + 48Ca reactions at 330 MeV and 310 MeV respectively. A lifetime RDDS technique, developed in collaboration with IKP Cologne, and result in the 48Ca region will be also presented. During 2009 the upcoming setup with the AGATA Demonstrator and PRISMA will start the experimental campaign at LNL.
