Effect of isospin-dependent cross-section on fragment production in the collision of charge asymmetric nuclei

Article

Abstract

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 \(^{124}{\rm X}_{n}+^{124}{\rm X}_{n}\), where n varies from 47 to 59 and for \(^{40}{\rm Y}_{m}+^{40}{\rm Y}_{m}\), 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.
