摘要
使用离线γ能谱法和厚靶－厚收集箔技术测量了２０—４６ＭｅＶ／ｕ１２Ｃ离子和铜相互作用中余核的前向平均反冲射程．导出了中心碰撞的线性动量转移．当轰击能量为２７．５ＭｅＶ／ｕ时，每个入射核子转移的线性动量达到１５５ＭｅＶ／ｃ的最大值．复合系统的最大激发能为每核子２．５ＭｅＶ．
By using off- line γ-ray spectroscopy in conjunction with thick target-thick catcher foil techniques,the mean forward recoil ranges have been measured for the residues produced from interaction of copper with 20 -46MeV/u 12Cions.From these data,linear momentum transfer for central collisions has been extracted. The linear momentum transfer per incident nucleon attains a maximum value of 155MeV/c at approximately 27.5MeV/u.The maximum excitation energy of the composite system is found to be 2.5MeV/u.
