Single-nucleon removal in relativistic and intermediate energy nucleus-nucleus collisions is studied using a generalization of Weizsäcker-Williams theory that treats each electromagnetic multipole separately. Calculations are presented for electric dipole and quadrupole excitations and incorporate a realistic minimum impact parameter, Coulomb recoil corrections, and the uncertainties in the input photonuclear data. Discrepancies are discussed. The maximum quadrupole effect to be observed in future experiments is estimated and also an analysis of the charge dependence of the electromagnetic cross sections down to energies as low as 100 MeV/nucleon is made.
利用对魏茨泽克 - 威廉姆斯理论的推广来研究相对论性和中能核 - 核碰撞中的单核子移除，该推广理论分别处理每个电磁多极子。给出了电偶极和四极激发的计算结果，并纳入了实际的最小碰撞参数、库仑反冲修正以及输入光核数据中的不确定性。讨论了差异。估计了未来实验中可观测到的最大四极效应，并对低至100 MeV/核子能量下电磁截面的电荷依赖性进行了分析。
