The angular distribution for the breakup of 8B-->7Be+p on a 58Ni target has been measured at an incident energy of 25.75 MeV. The data are inconsistent with first-order theories but are remarkably well described by calculations including higher-order effects. The comparison with theory illustrates the importance of the inclusion of the exotic proton halo structure of 8B in accounting for the data.
在入射能量为25.75 MeV的情况下，测量了8B在58Ni靶上发生8B→7Be + p破裂的角分布。这些数据与一阶理论不一致，但通过包含高阶效应的计算能得到很好的描述。与理论的比较说明了在解释这些数据时考虑8B的奇特质子晕结构的重要性。
