Abstract

Abstract: Measurements of neutron total cross sections of palladium in the energy region from 0.2 to 120 eV have been performed by using the time-of-flight method at the Pohang Neutron Facility. A group of high-purity natural palladium metallic plates with thicknesses of 0.5 and 1.0 mm is used for the neutron transmission measurement. Resonance parameters of 104 Pd, 105 Pd, 106 Pd, 108 Pd, and 110 Pd in the neutron energy range below 120 eV were extracted from the transmission ratios by using the multilevel R-matrix SAMMY code. The present results are compared with the evaluated data from ENDF/B-VII.1 and previous experimental data. The statistical analysis for nearest-neighbor level spacings in 105 Pd has been carried out to compare with the Wigner distribution.
