The γ-ray strength function method is devised to indirectly determine radiative neutron capture cross sections for radioactive nuclei. This method is applied here to the 107Pd (T1/2=6.5×106 yr) case. Photoneutron cross sections were measured for 105,106,108Pd near neutron threshold with quasimonochromatic laser-Compton-scattering γ-ray beams. These photoneutron cross sections as well as the reverse radiative neutron capture cross sections for 104,105Pd are used to provide constraints on the 107Pd(n,γ)108Pd cross section.
