首次在库仑势垒周围的能量范围内测量了放射性离子束 7 Be 和 8 B 在 208 Pb 靶上引起的核反应的弹性散射过程。在光学模型的框架内进行了大量的理论计算。 7 Be+ 208 Pb 反应的实验数据与理论预测之间取得了很好的一致性，而对更奇异的射弹 8 B 引起的反应动力学的全面理解仍然有待实现。还将给出两个系统破裂横截面的预测。
The elastic scattering process for the nuclear reactions induced by the Radioactive Ion Beams 7 Be and 8 B on a 208 Pb target was measured for the first time in the energy range around the Coulomb barrier. Extensive theoretical calculations within the framework of the optical model were performed. An excellent agreement between experimental data and theoretical predictions was achieved for the reaction 7 Be+ 208 Pb, while a comprehensive understanding of the reaction dynamics induced by the more exotic projectile 8 B is still far to be reached. Predictions of the cross section for the breakup for both systems will also be given.
