Abstract
Particle- coincidences from the () inelastic scattering reaction with 15-MeV protons are utilized to obtain -ray spectra as a function of excitation energy. The rich data set allows analyzsis of the coincidence data with various gates on excitation energy. For many independent data sets, this enables a simultaneous extraction of level density and radiative strength function (RSF). The results are consistent with one common level density. The data seem to exhibit a universal RSF as the deduced RSFs from different excitation energies show only small fluctuations provided that only excitation energies above MeV are taken into account. If transitions to well-separated low-energy levels are included, the deduced RSF may change by a factor of 2–3, which might be expected because of the involved Porter-Thomas fluctuations.
