CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe 16O+58Ni deep-inelastic collision has been investigated at Elab(16O) = 132 MeV by using coincident charged particle techniques. Exclusive data of the projectilelike fragments (C, N, and O) and their associated light charged particles (protons and a particles) were collected in coincidence. The experiment has been performed at the IReS Strasbourg VIVITRON Tandem facility by using the ICARE charged particle multidetector array. The measured velocity diagrams and in-plane angular correlations have been analyzed by a semiclassical model that combines equilibrium and nonequilibrium processes of a deep-inelastic scattering reaction. Following the hypothesis of a sequential process, this closed-form theoretical approach is applied to the measured [(C,N,O)-p] and [(C,N,O)-α] differential multiplicities. Estimates on polarization phenomena and on "decay times" are used to provide information about deep-inelastic scattering in 16O+58Ni at 8.25 MeV/nucleon.

| Abstract: | The 16O+58Ni deep-inelastic collision has been investigated at Elab(16O) = 132 MeV by using coincident charged particle techniques. Exclusive data of the projectilelike fragments (C, N, and O) and their associated light charged particles (protons and a particles) were collected in coincidence. The experiment has been performed at the IReS Strasbourg VIVITRON Tandem facility by using the ICARE charged particle multidetector array. The measured velocity diagrams and in-plane angular correlations have been analyzed by a semiclassical model that combines equilibrium and nonequilibrium processes of a deep-inelastic scattering reaction. Following the hypothesis of a sequential process, this closed-form theoretical approach is applied to the measured [(C,N,O)-p] and [(C,N,O)-α] differential multiplicities. Estimates on polarization phenomena and on "decay times" are used to provide information about deep-inelastic scattering in 16O+58Ni at 8.25 MeV/nucleon. |
