Abstract
Recently published study on the -ray energy dependence of photon strength functions (PSFs) from the population of low-lying levels in the reaction set out to answer some important questions related to the PSFs below the neutron separation energy in the Mo region. In this paper we discuss in detail actual relations of the quantities measured in this reaction to the PSFs and check the consistency of several available PSF models with experimental data. A broad variety of models was found to be consistent with experimental data at low . Although the photon strength very likely increases with decreasing energy at MeV, the data are unable to clearly differentiate whether the decrease follows the shape proposed from Oslo-type experiments or predictions of the generalized Lorentzian model. The PSF shape at energies of MeV is steeper than predicted by any standard model.
