The excitation functions for the production of (82)Sr and other radionuclides produced in the proton bombardment of rubidium were measured by means of the activation technique. Stacks were assembled from RbCl targets, aluminium and copper monitor foils and bombarded with protons of energy up to 100 MeV and nominal current 0.1 microA. The measured data were compared with the theoretical calculations obtained by means of ALICE-IPPE, and also with previously published data. The measured data sets exhibit good agreement at incident energies below 45 MeV and greater than 60 MeV but show large discrepancies in the energy range between these values. The ALICE-IPPE calculations evidently overestimate all reported experimental cross sections, in particular overestimating the present data by a factor of 1.6. Notwithstanding the fact that there are discrepancies in the cross sections, good agreement is found with regards to the shape of the excitation function.
通过活化技术测量了质子轰击铷时产生（82）Sr及其他放射性核素的激发函数。堆叠装置由RbCl靶、铝和铜监测箔组成，并用能量高达100 MeV、标称电流0.1微安的质子进行轰击。将测量数据与通过ALICE - IPPE获得的理论计算结果进行比较，同时也与先前发表的数据进行比较。测量数据集在入射能量低于45 MeV和高于60 MeV时表现出良好的一致性，但在这些值之间的能量范围内存在较大差异。ALICE - IPPE计算明显高估了所有报道的实验截面，特别是将当前数据高估了1.6倍。尽管截面存在差异，但在激发函数的形状方面发现了良好的一致性。
