Study of nuclear dynamics of neutron-rich colliding pair at energy of vanishing flow
The collective transverse in-plane flow has been used extensively over the past three decades to study the properties of hot and dense nuclear matter., i.e., the nuclear matter equation of state (EOS) and in-medium nucleon-nucleon cross section. It has been reported to be highly sensitive to the entrance channel parameters like incident energy, colliding geometry and system size. The energy dependence of flow led to its disappearance at a particular incident energy called energy of vanishing flow (EVF) or balance energy (Ebal). A large number of theoretical studies have been carried out in the past studying the sensitivity of Ebal to the system size and colliding geometry. Role of isospin degree of freedom in collective transverse in-plane flow and its disappearance has also been a matter of great interest for the past decade [1]. The availability of radioactive ion beams (RIBs) around the world helps in carrying out the studies on the matter lying far away from the stability line. A number of studies have been carried out in the recent past to see the role of isospin degree of freedom in collective flow and its disappearance [1, 2]. In Ref. [3] author and others studied the isospin effects in Ebal at all the colliding geometries. A very few studies have been carried out to study other related phenomena at Ebal of the neutron-rich systems. An important quantity which reflects the dynamics in a heavy-ion collision is the density and temperature reached in a reaction. In the present paper, we study the density and temperature reached in heavy-ion reactions of neutron-rich matter at Ebal using isospin-dependent quan-
