Theoretical Analysis of Gamma-ray Strength Function for Pd Isotopes

Gamma-ray strength functions of Pd isotopes were investigated by using measured photonuclear reaction cross sections and neutron capture reaction data. The present results calculated by nuclear reaction calculation code CCONE well reproduce the available experimental data. It is found from the evaluation of capture γ-ray spectra that additional resonances with a variety of strength are present at around γ-ray energies of 5 to 6 MeV. The calculated values of s-wave γ strength function for 106,108Pd are 40% smaller than compiled values derived from resolved resonance data.
