The isoscaling behavior in the reaction system of 58,64Ni + 9Be has been studied by using the heavy-ion phase-space exploration(HIPSE) model. The extracted isoscaling parameters α and β for both heavy and light fragments for HIPSE model calculations are in good agreement with recent experimental data.The investigation shows that the parameters in the HIPSE model have some effect on the isoscaling parameter.The isoscaling parameters for hot and cold fragments have been extracted.
