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

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
