1. Multinucleon transfer reactions studied with the PRISMA magnetic spectrometer

Author

Szilner, Suzana, Corradi, L., Pollarolo, G., Beghini, S., Farnea, E., Fioretto, E., Gadea, A., Haas, F., Latina, A., Lenzi, S., Marginean, N.M., Montagnoli, G., Napoli, D.R., Pokrovskiy, I.V., Scarlassara, F., Steafnini, A.M., Trotta, M., Ur, C.A., Harissopulos, S., Demetriou, P., and Julin, R.

Subjects

Abstract

Multinucleon transfer reactions with ^40Ca beams on closed shell nuclei ^96Zr and ^208Pb at energies close to the Coulomb barrier were studied using magnetic spectrometers. The comparison between data and calculations, based on semiclassical models, allowed to identify the different degrees of freedom that influence the evolution of the reaction, like deformation, single, and pair transfer modes.

Subjects
Ca induced fusion close to the Coulomb barrier, quasi-fission mechanism, fusion inhibition effect, Nuclear Theory, Nuclear Experiment
Abstract

Experimental results on the fusion inhibition effect near the Coulomb barrier due to the onset of the quasi-fission mechanism are presented. The investigation was focused on reactions induced by 48Ca projectiles on different heavy targets and comparing them to reactions induced by light ions such as ^12C and ^16O leading to the same compound nuclei. Cross sections and angular distributions of evaporation residues and fission fragments have been measured.

Subjects
CLARA-PRISMA, neutron-rich-nuclei
Abstract

CLARA is an array of 25 Clover (EUROBALL type) Ge detectors, placed at the target position of the large acceptance magnetic spectrometer PRISMA. Due to the granularity of the CLARA Ge array (100 crystals), the photopeak efficiency ( 3%) and the PRISMA large acceptance ( 80 msr, and 20% Δ p/p), the setup is an excellent tool to investigate the structure of neutron-rich nuclei, populated in multinucleon transfer reactions and deep inelastic collisions with stable beams. Since March 2004 the setup is fully operational, and since then several experiments have been performed, with beams delivered by the LNL XTU-Tandem and the ALPI linac. In this contribution the preliminary outcome of the first experiments is shown.
