Particle-γ coincidences from the 46 Ti(p, p γ) 46 Ti inelastic scattering reaction with 15-MeV protons are utilized to obtain γ-ray spectra as a function of excitation energy. The rich data set allows analysis 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 3 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 the involved Porter-Thomas fluctuations.

The nuclear level density and the γ-ray strength function have been determined for 43 Sc in the energy range up to 2 MeV below the neutron separation energy using the Oslo method with the 46 Ti(p, α) 43 Sc reaction. A comparison to 45 Sc shows that the level density of 43 Sc is smaller by an approximately constant factor of two. This behaviour is well reproduced in a microscopical/combinatorial model calculation. The γ-ray strength function is showing an increase at low γ-ray energies, a feature which has been observed in several nuclei but which still awaits theoretical explanation.
