title: Integral excitation functions for natKr + p up to 116 MeV and optimization of the production of 81Rb for (81m)Kr generators.
abstract: Effective cross-sections for the production of 79,81,81m,82m,83,84,84m,86Rb, (77,79,85m)Kr and 77,82Br in the bombardment of natKr with protons were measured from threshold up to 116 MeV. Thick-target production-rate curves based on the measured integral excitation functions were also derived for 81,82m,83,84,86Rb, and the optimum incident energy for the production of 81Rb/(81m)Kr, as a function of the target thickness in MeV, was determined. Geometry-dependent hybrid-model calculations performed by means of the computer code ALICE/85/300 were found to be in good agreement with the experimental results as well as the derived thick-target production-rate curves.
