Opis

The pre equilibrium model (thermodynamic model) is used to study the P1+P1, S32+O16, Au197+Au197 and Ne20+U238 collisions at 20 and 130 AGeV. A frame of reference is assumed to coincide with the center of the target, and the projectile is located at a position r, with the impact parameter. The relative projectile density, (r, b) is then calculated. The function (r, b) shows peaks at different values of radial distance(r) and for different collisions. The parameter is then used to evaluating the temperature and its gradient inside the nuclear matter. The proton density function in its equilibrium form is calculated over the effective range of the thermodynamic system. The energy spectra of proton, kion and pion produced by Au+Au collision at 20&130 GeV are studied along with the spatial variation of the function fo(r, p). Completestopping of Au projectiles with Au target is predicted.

Aish, MohammedDr M. M. Aish have got his Ph. D. in June 2014 from Altai State Technical University, Russia. Dr Aish studied the deformation and fracture characteristics of metallic nanowires and alloys depending on their shape and size. He have research interest involves studying and modeling the structure of nano-systems and complex materials.
