摘要The fragment production cross sections for 140MeV/nucleon 48,40Ca9Be reactions are calculated by the heavy-ion phase space exploration (HIPSE) model. Isoscaling behavior is observed. The isoscaling parameters α and β for both heavy and light fragments from the HIPSE model calculations are in good agreement with the experimental data. It is shown that the potential parameters in the HIPSE model have very little effect on the isoscaling parameters. The effect of the excitation energy and evaporation on the isoscaling behavior is also discussed.
