Title:Antisymmetrized molecular dynamics approach for cluster production in heavy-ion collisions
Speaker: Prof. Akira Ono
Abstract:
In a wide energy range from Fermi energies to several hundred MeV/nucleon, we know that a heavy-ion collision produces a lot of clusters such as deuterons, tritons, alpha particles, and heavier fragment nuclei. Cluster production reflects quantum many-body correlations and thermodynamic properties of excited nuclear systems. We have been developing transport models such as the antisymmetrized molecular dynamics (AMD) model to describe cluster production within a time-dependent framework with microscopic ingredients. Recent versions of AMD incorporate cluster correlations explicitly, which has drastic impacts not only on the cluster yields but also on the global evolution of the system. In this talk, I will include applications of AMD to fragmentation of light projectile nuclei such as 12C, 20Ne and 32S, and other studies to extract information on nuclear symmetry energy from cluster observables.
About speaker:
Prof. Ono finished his Ph.D. in science at Kyoto University in 1995. After working at RIKEN as a postdoctoral fellow for about a year, he got a permanent position at Tohoku University in 1996. His main research interest has been the many-body dynamics in nuclear reactions and the properties of nuclear matter realized during reactions. Recently, he is participating in several international collaborations, including the transport model evaluation project.
