FRAGMENTATION REACTION AND PRODUCTION OF RADIOACTIVE NUCLEAR BEAMS

本文总结了中能重离子碰撞产生同位素分布的计算方法和模型 ,包括参数化公式 ,擦碎模型和统计擦碎模型。介绍了模型的物理基础和计算方法 ,并讨论了对擦碎模型和统计擦碎模型的修正。同时用统计擦碎模型探讨了碎裂反应产生的同位素分布的同位旋效应。然后介绍了放射性核束的产生方法 ,并对放射性束流物理的发展前景作了简要介绍。

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.
