Abstract: Spectrum-averaged cross sections of the reactions 85Rb(n,α)82xm + gBr, 85Rb(n,2n)84xm + gRb and 85Rb(n,p)85mKr were measured over the fast neutron spectrum with neutron energies from 0.5 to 20 MeV of a TRIGA reactor. In addition, data for the well-investigated reactions 113In(n,n´)113mIn and 115In(n,n´)115mIn were re-measured to confirm the validity of the neutron spectrum and the experimental techniques. The new results of the present measurements were used to perform integral tests of evaluated excitation functions in the latest nuclear data libraries, including ENDF/B-VIII.1, JEFF-3.3, JEFF-3.1/A, JENDL-5, IRDF-1.05, and TENDL-2023. The experimental data generally agree with the integrated values from the excitation functions within 8 %, with a few exceptions. For the reaction 85Rb(n,2n)84xm + gRb, the integrated value from the ENDF/B-VIII.1 library is higher by 17 % than the measured integral value. The JEFF-3.1/A and JENDL-5 libraries for the reaction 85Rb(n,p)85mKr appear to require improvement.
