Neutron-induced reaction cross section measurements for palladium isotopes at 14.77 ± 0.17 MeV with covariance analysis

The nuclear reaction cross sections for 110 Pd(n,2n) 109m Pd, 102 Pd(n,2n) 101 Pd, 106 Pd(n,p) 106m Rh, 110 Pd (n,2n)109gPd 109g Pd and 105 Pd(n,p) 105 Rh have been measured at the neutron energy of 14.77 +/- 0.17 MeV by using the method of activation and off-line gamma- 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.
