Heavy-ion collisions; multifragmentation; symmetry energy.

To understand the role of isospin effects on fragmentation due to the collisions of charge asymmetric nuclei, we have performed a complete systematical study using isospin-dependent quantum molecular dynamics model. Here simulations have been carried out for ${}^{124}X_n + {}^{124}X_n$ ,where 𝑛 varies from 47 to 59 and for ⁴⁰Y$_m$ + ⁴⁰Y$_m$ , where 𝑚 varies from 14 to 23. Our study shows that isospin-dependent cross-section shows its influence on fragmentation in the collision of neutron-rich nuclei.
