Title: Influence of statistical sequential decay on isoscaling and symmetry energy coefficient in a gemini simulation

Abstract

Extensive calculations on isoscaling behavior with the sequential-decay model gemini are performed for the medium-to-heavy nuclei in the mass range A=60-120 at excitation energies up to 3 MeV/nucleon. The comparison between the products after the first-step decay and the ones after the entire-steps decay demonstrates that there exists a strong sequential decay effect on the final isoscaling parameters and the apparent temperature. Results show that the apparent symmetry energy coefficient {gamma}{sub app} does not reflect the initial symmetry energy coefficient C{sub sym} embedded in the mass calculation in the present gemini model.
