Abstract
Photoneutron cross sections were measured for Mo, Mo, Mo, Mo, Mo, and Mo near the neutron threshold with quasi-monochromatic laser-Compton scattering rays. The photoneutron data were analyzed with the Skyrme Hartree-Fock-Bogoliubov (HFB) plus quasiparticle random phase approximation (QRPA) model and the axially symmetric-deformed Gogny HFB plus QRPA model of -ray strength. Combining the -ray strength function constrained by the present photoneutron data with either the nuclear resonance fluorescence data or the updated Oslo data to supplement the data below the neutron threshold, a thorough analysis of the reverse cross sections is made whenever measurements are available. The Oslo data and the corresponding uncertainties are updated based on the latest results of the -wave neutron spacing and the average radiative width determined in particular for Mo. Finally, radiative neutron capture cross sections for two radioactive nuclei, Mo and Mo, are deduced with the -ray strength function method.
