EVALUATION OF SOME NUCLEAR LEVEL DENSITY AND RADIATIVE STRENGTH FUNCTION MODELS BASED ON EXPERIMENTAL TWO-STEP GAMMA-CASCADE INTENSITIES OF 51V(nth, 2γ)52V REACTION
Main Article Content
Abstract
Some nuclear level density (NLD) and radiative strength function (RSF) models, including three phenomenological NLD and three phenomenological RSF models, and a microscopic model that simultaneously determines the NLD and RSF, have been evaluated based on the experimental two-step gamma-cascade intensities obtained from the 51V(nth, 2γ)52V experiment at the Dalat Nuclear Research Institute. Among the models evaluated, the exact pairing coupled with the independent-particle and phonon-damping models best explains the experimental data and is, thus, considered to be the most credible model to predict the NLD and RSF of 52V. To have a more comprehensive evaluation, forthcoming studies should assess a larger variety of models in particular, those that employ the mean-field Hartree-Fock-Bogoliubov approximation, as well as other (nth, 2γ) experiments.
