Measurement of the integrated cross section of 110Pd(γ,n)109mPd, 110Pd(γ, n)109gPd, and 110Pd(γ,x)108mRh reactions with 70 MeV bremsstrahlung

초록

We measured the integrated cross sections of 110Pd(gamma,n)109mPd, 110Pd(gamma,n)109gPd and 110Pd(gamma,x)108mRh 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 gamma-ray spectrometry. The induced activity of radionuclides was measured with a high-purity germanium (HPGe) detector and necessary corrections for gamma-ray interferences were made. The integrated cross section of the studied reactions was measured relative to that of the monitor reaction 27Al(gamma,2pn)24Na. 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 gamma-strength functions to determine which combinations best fit the experimental results. The present results are measured for the first time.
