Abstract

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 ${}^{107}{Pd}$ ( $T_{1 / 2} = 6.5 \times 10^{6}$ yr) case. Photoneutron cross sections were measured for ${}^{105, 106, 108}{Pd}$ 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 ${}^{104, 105}{Pd}$ are used to provide constraints on the ${}^{107}{Pd}$ ( $n, γ$ ) ${}^{108}{Pd}$ cross section.
