Photoneutron cross section measurements were made for Au in the entire energy range of the (gamma,n) channel based on a direct neutron counting with quasi-monochromatic gamma-rays produced in inverse Compton scattering of laser photons with relativistic electrons. The data were analyzed by a least-squares method to deduce photoneutron cross sections. The analysis significantly reduced experimental uncertainties compared with those resulting from the photon difference method. The result is compared with the previous data by direct neutron counting with gamma-rays produced in positron annihilation in flight and by photoactivation with bremsstrahlung. The present data are in good agreement with the previous data near the neutron threshold, while there remain some discrepancies between the present and the previous data above 10 MeV.

The gamma-ray strength function (gamma SF) interconnects radiative neutron capture and photoneutron emission as a common ingredient in the statistical model. Outlined here is an indirect method of determining radiative neutron-capture cross sections for unstable nuclei based gamma-ray strength function. Application examples of the gamma SF method are demonstrated.

Photoneutron cross sections for Zr-90 near neutron threshold were examined with a photon difference technique using laser Compton scattering gamma-ray beams. The cross section decreasing in the vicinity of neutron threshold exhibited a steep rise within 150 keV above the threshold. We draw attention to a possible relation of this striking behavior to the 3P valence neutron resonance known in neutron capture in the mass region A approximate to 90.

Photoneutron cross sections were measured for Au in the entire energy range of the (gamma,n) channel based on a direct neutron-counting technique with quasimonochromatic gamma rays produced in inverse Compton-scattering of laser photons with relativistic electrons. We present results of the measurement in comparison with the past data.

The gamma-ray strength function method is devised to indirectly determine radiative neutron capture cross sections for radioactive nuclei. This method is applied here to the Pd-107 (T-1/2 = 6.5 x 10(6) yr) case. Photoneutron cross sections were measured for Pd-105,Pd-106,Pd-108 near neutron threshold with quasimonochromatic laser-Compton-scattering gamma-ray beams. These photoneutron cross sections as well as the reverse radiative neutron capture cross sections for Pd-104,Pd-105 are used to provide constraints on the Pd-107(n,gamma)Pd-108 cross section.
