Abstract: Cross sections of proton-induced nuclear reactionson enriched 86Sr target were measured by the activationtechnique up to proton energies of 44 MeV. The isomericcross-section ratios for 86m,gY and 85m,gY as a function ofprojectile energy were deduced from their measured data.The present experimental data for the nuclear reaction products,namely 86mY, 86g+xmY, 85mY, 85gY, 84Rb and 83Rb werecompared with the results of nuclear model calculations usingthe code TALYS, which combines the statistical, precompound,and direct interactions. In general, the experimentalcross-section data as well as the isomeric cross-section ratiosare reproduced well by the model calculations, provided theinput model parameters are properly chosen and the levelstructure of the product nucleus is thoughtfully considered.The quality of the agreement between experimental data andmodel calculations was numerically quantified. For productsformed via emission of a light complex particle as well asmulti-nucleons (e.g., α and 2p2n), the contribution of thelatter process starts increasing when its energy threshold iscrossed.
