Nuclear reaction cross-section data in the medium-mass region are important for applications in medical isotope production, accelerator technology, astrophysics, and reactor design. Proton-induced reactions on Rb–Br isotopes have been investigated using the activation technique. Thin RbBr targets were irradiated with 15 MeV protons at the BARC-TIFR Pelletron Facility, India. The irradiation setup was modelled using Monte Carlo transport codes MCNP and PHITS to estimate proton energy degradation within the targets, yielding effective mean energies of 12.8 ± 2.1 MeV and 5.2 ± 2.6 MeV. Induced activities were measured using a calibrated HPGe detector. Cross sections for the reactions ⁸⁵,⁸⁷Rb(p, n)⁸⁵,⁸⁷Sr and ⁷⁹Br(p, n)⁷⁹Kr were determined, including the first measurement of the ⁸⁷Rb(p, n)⁸⁷Sr reaction at 12.8 ± 2.1 MeV. The experimental results are compared with theoretical predictions obtained using TALYS 2.0 and EMPIRE 3.2.2. A systematic covariance analysis has been performed to quantify uncertainties arising from model parameters. The results provide new experimental constraints on nuclear reaction models in the medium-mass region and demonstrate the effectiveness of combining Monte Carlo transport simulations with reaction model calculations for accurate interpretation of activation data. The present measurements, supported by covariance analysis and parameter estimation, provide valuable input for nuclear data evaluation and improve the reliability of medical isotope production.
