Study of participant-spectator matter, thermalization and other related phenomena for neutron-rich colliding pair

We study the participant-spectator matter, density and temperature reached in heavy-ion reactions of neutron-rich systems having N/Z varying from 1.0 to 2.0 at 50 and 250 MeV/nucleon. The N/Z dependence of these quantities is also investigated. Our results show a weak dependence on the N/Z ratio of the system on these quantities. We also shed light on the role of N/Z ratio on the thermalization achieved in a reaction. We find similar weak N/Z dependence on thermalization also.Comment: 14 pages, 6 figure

Isospin effects on the system size dependence of balance energy in heavy-ion collisions

We study the effect of isospin degree of freedom on balance energy throughout the mass range between 50 and 350 for two sets of isobaric systems with N/A = 0.5 and 0.58. Our fndings indicate that different values of balance energy for two isobaric systems may be mainly due to the Coulomb repulsion. We also demonstrate clearly the dominance of Coulomb repulsion over symmetry energy.Comment: EFB 2010, August29-september03, 2010 Salamanca, SPAI

Impact parameter dependence of isospin effects on the mass dependence of balance energy

We study the effect of isospin degree of freedom on the balance energy as well as its mass dependence throughout the mass range 48-270 for two sets of isobaric systems with N/Z = 1 and 1.4 using isospin-dependent quantum molecular dynamics (IQMD) model. Our fndings reveal the dominance of Coulomb repulsion in isospin effects on balance energy as well as its mass dependence throughout the range of the colliding geometry.Comment: International Symposium on Quasifission Process in Heavy Ion Reactions, Messina (ITLAY) November 8-9, 201

On the participant-spectator matter and thermalization of neutron-rich systems in heavy-ion collisions

We study the participant-spectator matter at the energy of vanishing flow for neutron-rich systems. Our study reveals similar behaviour of articipant-spectator for neutron-rich systems as for stable systems and also points towards nearly mass independence behaviour of participant-spectator matter for neutron-rich systems at the energy of vanishing flow. We also study the thermalization reached in the reactions of neutron-rich systems
