ABSTRACT
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.
