Isoscaling of Z=1 to 17 fragments from the reaction of $^{86,78}$Kr with $^{64,58}$Ni targets at 35MeV/nucleon

ORAL

Abstract

Isoscaling is the exponential relationship found when comparing the ratio of the yields between neutron-rich and neutron-poor systems produced in nuclear reactions. The reactions of $^{86,78}$Kr projectiles on $^{64,58}$Ni targets at 35MeV/nucleon were studied with the NIMROD-ISiS array. The 4$\pi $ coverage and isotopic resolution (through Z = 17) of the NIMROD-ISiS array allows reconstruction of the quasi-projectile in both Z and A. Well-defined quasi-projectile sources were extracted from the data. Isoscaling was first attempted by comparing the yields between different systems with little success. The yields from three bins in the N/Z of the quasi-projectile (less than 1, between 1 and 1.2, and greater than 1.2) were then compared between systems with similar results. Finally, the yields from the neutron-rich and neutron-poor quasi-projectiles within each system were isoscaled successfully. The isoscaling of Z = 1-17 will be presented.
