| Abstract: | The calculation method and models for the isotopic distribution produced in heavy ion collisions at intermediate energies which includes the parameterization formula, the abrasion?ablation model and the statistical abrasion?ablation model were reviewed. The physical foundation of these models and their calculation method were introduced,and the modification to these models were discussed. Then the isospin effect of the isotopic distribution produced in the fragmentation reaction was investigated via the modified statistical abrasion?ablation model.At last the production method of radioactive nuclear beams and its perspective were introduced briefly. |
| Keywords: | fragmentation radioactive nuclear beams (RNB) abrasion?ablation model isospin eff |
