Description
The applicability of the sum-coincidence measurements of two-step cascade γ-ray spectra to determination of photon strength functions at intermediate γ-ray energies (3 divided 4 MeV) is discussed. An experiment based on thermal neutron capture in Nd was undertaken at the BNL High Flux Beam Reactor to test this method. To understand the role of various uncertainties in similar experiments a series of model calculations was performed. We present an analysis of our experimental data which demonstrates the high sensitivity of the method to E1 and M1 photon strength functions. (author). 5 refs, 7 figs
