Potential parameters have minimal impact on isoscaling behavior

Excitation energy and evaporation influence isoscaling properties

Abstract

The fragment production cross sections for 140 MeV/nucleon $^{48,40}$Ca$+^{9}$Be reactions have been calculated by the Heavy Ion Phase Space Exploration (HIPSE) model. Isoscaling behavior is observed. The isoscaling parameters $\alpha$ and $\beta$ for both heavy and light fragments from HIPSE model calculations are in good agreement with the experiment data. Studies show that the potential parameters in the HIPSE model have very small effect on the isoscaling parameters. The effect of the excitation energy and evaporation on the isoscaling behavior has also been discussed.
