The nuclear reaction cross sections for Pd(n,2n)Pd, Pd(n,2n)Pd, Pd(n,p)Rh, Pd(n,2n)Pd and Pd(n,p)Rh have been measured at the neutron energy of 14.77 ± 0.17 MeV by using the method of activation and off-line γ-ray spectrometry. The uncertainties in the various nuclear parameters in the measured reactions and their correlations were estimated by using covariance analysis. The present data were compared with literature data from the EXFOR database and nuclear data libraries, including ENDF/B-VIII.0, JEFF-3.3, JENDL-5.0 and TENDL-2021. Theoretical model calculations for the cross-sections are performed with the TALYS-1.96 nuclear model code with optimized parameters. There is good agreement between the measured, literature and evaluated data. The results are important for shielding applications in the radiation fields involving neutrons.
