Role of asymmetry of the reaction and momentum dependent interactions on the balance energy for neutron rich nuclei

We present a systematic study of disappearance of flow i.e. balance energy $E_{bal}$ for an isotopic series of Ca with N/Z varying from 1 to 2 for different density dependences of symmetry energies. We also extend this study for asymmetric reactions having radioactive projectile and stable target.Comment: 3 pages, 2 figs, DAE BRNS Symposium on Nuclear Physics Dec 26-30, (2011), Visakhapatnam A.P.

Effect of isospin dependence of cross section on symmetric and neutron rich systems

We aim to explore the effect of isospin dependence of cross section on symmetric and neutron rich system. We also aim to explore whether the analysis is affacted if one discusses in terms of "$E_{bal}$ as a function of N/Z or N/A" of the system.Comment: 3 pages, 1 figs, DAE BRNS Symposium on Nuclear Physics Dec 26-30, (2011), Visakhapatnam A.P.

Effect of isospin degree of freedom on the counterbalancing of collective transverse in-plane flow

Here we aim to understand the effect of isospin dependence of cross section and Coulomb repulsion on the counterbalancing of collective flowComment: 3 pages, 2 figs, DAE BRNS Symposium on Nuclear Physics Dec 26-30, (2011), Visakhapatnam A.P. INDI

Observable to explore high density behaviour of symmetry energy

We aim to see the sensitivity of collective transverse in-plane flow to symmetry energy at low as well as high densities and also to see the effect of different density dependencies of symmetry energy on the same.Comment: 3 pages, 2 figs, DAE BRNS Symposium on Nuclear Physics Dec 26-30, (2011), Visakhapatnam A.P.

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

Model ingredients and peak mass production in heavy-ion collisions

We simulate the central reactions of $^{20}$Ne+$^{20}$Ne, $^{40}$Ar+$^{45}$Sc, $^{58}$Ni+$^{58}$Ni, $^{86}$Kr+$^{93}$Nb, $^{129}$Xe+$^{118}$Sn, $^{86}$Kr+$^{197}$Au, and $^{197}$Au+$^{197}$Au at different incident energies for different equations of state, different binary cross sections and different widths of Gaussians. A rise-and-fall behavior of the multiplicity of intermediate mass fragments (IMFs) is observed. The system size dependence of peak center-of-mass energy E$_{c.m.} ^{max}$ and peak IMF multiplicity $^{max}$ is also studied, where it is observed that E$_{c.m.}^{max}$ follows a linear behavior and $^{max}$ shows a power-law dependence. A comparison between two clusterization methods, the minimum spanning tree and the minimum spanning tree method with binding energy check (MSTB), is also made. We find that the MSTB method reduces the $^{max}$, especially in heavy systems. The power-law dependence is also observed for fragments of different sizes at E$_{c.m.} ^{max}$ and the power-law parameter $\tau$ is found to be close to unity in all cases except A$^{max}$.Comment: 6 Figures, 7 page
