Influence of secondary decay on chemical freeze-out temperature isospin effect measurement

The influence of sequential decay on isospin dependence of isotope yield ratio temperatures is studied and a systematic study of isotope temperatures is presented for heavy-ion collisions at 600 MeV/nucleon via the isospin-dependent quantum molecular dynamics model in the company of the statistical decay model (GEMINI). Calculations show that the isospin dependence of the isotope yield ratio temperature is not affected by secondary decay.
