Do light nuclei display a universal gamma-ray strength function?
Popis výsledku v původním jazyce
In this work we focus on properties in the quasi-continuum of light nuclei. Generally, both level density and gamma-ray strength function (gamma-SF) differ from nucleus to nucleus. In order to investigate this closer, we have performed particle-gamma coincidences using the reactions (p; p'), (p; d) and (p; t) on a Ti-46 target. In particular, the very rich data set of the Ti-46(p; p') Ti-46 inelastic scattering reaction allows analysis of the coincidence data for many independent data sets. Using the Oslo method, we find one common level density for all data sets. If transitions to well-separated low-energy levels are included, the deduced gamma-SF may change by a factor of 2 - 3, due strong to Porter-Thomas fluctuations. However, a universal gamma-SFwith small fluctuations is found provided that only excitation energies above 3 MeV are taken into account. The nuclear structure of the titaniums is discussed within a combinatorial quasi-particle model, showing that only few Nilsson orb
