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
Participant-spectator matter at the energy of vanishing flow
We aim to study the participant-spectator matter over a wide range of
energies of vanish- ing flow and masses. For this, we have employed different
model parameters at central and semi-central colliding geometries. A nearly
mass independent nature of the participant matter has been obtained at the
energy of vanishing flow. Further, participant matter can also act as an
indicator to study the degree of thermalization.Comment: Proceedings of the International Symposium on Nuclear Physics, Mumbai

Sensitivity of the transverse flow towards symmetry energy
We study the sensitivity of transverse flow towards symmetry energy in the
Fermi energy region as well as at high energies. We find that transverse flow
is sensitive to symmetry energy as well as its density dependence in the Fermi
energy region. We also show that the transverse flow can address the symmetry
energy at densities about twice the saturation density, however it shows the
insensitivity towards the symmetry energy at densities 2.
The mechanism for the sensitivity of transverse flow towards symmetry energy as
well as its density dependence is also discussed.Comment: Phys. Rev. C (in press)2011 14 pages, 6 figure
