摘　　要：本文对最高束流能量为290 A MeV的^(12)C核诱发铝靶核反应射弹碎裂电荷变化反应总截面及碎片粒子产生分截面进行研究.结果显示射弹碎裂电荷变化总截面及碎片粒子产生分截面在误差范围内与束流能量无关,核碎裂电荷变化总截面计算结果与Bradt-Peter公式及PHITS,NUCFRG2理论模型预测值一致,碎片粒子产生分截面值与NUCFRG2理论模型预测值一致.The total charge-changing reaction cross-sections and the partial cross-sections of projectile fragments production for the fragmentation of12 C on Al target at the highest energy of 290 A Me V is investigated. It is found that the total charge-changing reaction cross-sections and the partial cross-sections of projectile fragments production for the fragmentation is independent of the beam energy. The total charge-changing reaction cross section is the same as the prediction of Bradt-Peters semi-empirical formula,PHITS and NUCFRG2 models. The partial cross section of projectile fragments production is the same as the prediction of NUCFRG2 model.
