中文摘要：

在多源理想气体模型的框架内,用一个关于末态粒子多重数分布的统一描述,研究了低能重离子诱导反应中轻带电粒子和蒸发剩余物的能谱。在同一个激发的复合核中,每个源对带电粒子和蒸发剩余物均贡献一个指数分布的能谱。计算结果与158,170,180和200MeV20Ne＋12C反应中,轻带电粒子和蒸发剩余物能谱的实验结果符合。

英文摘要：

Using a unified description on multiplicity distributions of final-state particles,the energy spectra of light charged particles and evaporation residues in heavy ion induced reactions at low energy are studied in the framework of a multisource ideal gas model.Each source in an excited composite contributes energy spectra of light charged particles and evaporation residues to be an exponential law.The calculated results are compared and found to be in agreement with the expe-rimental data of inclusive and exclusive energy distributions for light charged particles and evaporation residues measured in the 20Ne（158,170,180,and 200 MeV） ＋ 12C reactions.
