Isospin effect of projectile fragment yields

摘要：

Isospin asymmetry is very important in the nuclear equation of state (EOS),isotope yield from the projectile fragments can give information of the reaction process.In this paper projectile fragment yields are measured in the collision 36,40Ar+64 Ni at incident energy 50 MeV/u with different isospin asymmetry project 36,40Ar,data analysis,particle identification and event selection are described.Isotope yields axe compared in these two reactions,and are also compared with the empirical parametrization of fragmentation cross-section calculated by EPAX.
