Abstract

Abstract: We measured the integrated cross sections of 110 Pd(γ, n) 109m Pd, 110 Pd(γ, n) 109g Pd and 110 Pd(γ, x) 108m Rh reactions in the energy range from the reaction threshold to 70 MeV bremsstrahlung end-point energy. Measurements were performed by means of the activation method in combination with off-line γ-ray spectrometry. The induced activity of radionuclides was measured with a high-purity germanium (HPGe) detector and necessary corrections for γ-ray interferences were made. The integrated cross section of the studied reactions was measured relative to that of the monitor reaction 27 Al(γ, 2pn) 24 Na. Current results are compared with theoretical predictions using the TALYS-1.9 statistical nuclear model code. Calculations were performed using six different level density models in combination with eight γ- strength functions to determine which combinations best fit the experimental results. The present results are measured for the first time. Highlights: Measured the integrated cross sections of 110Pd(γ, n)109g, mPd and 110Pd(γ, x) 108m Rh reactions. Results were determined relative to that of the 27Al(γ, 2pn) 24 Na monitoring reaction. Compared with the theoretical predictions obtained from the TALYS 1.9.
