摘要
使用离线ｒ能谱法和厚靶－厚收集箔技术测量了２０－４６ＭｅＶ／ｕ￣（１２）Ｃ离子和Ｃｕ相互作用中剩余核的前向平均反冲射程。根据这些数据得到了所有碰撞参数积分的平均线性动量转移和初始复合体系的平均激发能，实验结果与文献值吻合较好。
In the reaction of 20-46MeV/u with Cu,the mean forward recoil ranges of some 41residual nuclei are measured with thick target-thick catcher foil techniques in conjunction withoff-line r-ray spectroscopy. These data are used to obtain the average linear momentum transferintegrated over all impact parameters. The average linear momentum transfer is found to attain amaximum value of 155MeV/c at 27.5 MeV/u. The mean excitation energies at higherbombording energies reached about 103MeV,corresponding to a nuclear temperature of3.5MeV. The experimental results are compared with reference valus.
