Microcanonical entropies and radiative strength functions of $^{50,51}$V

Abstract
The level densities and radiative strength functions (RSFs) of $^{50,51}$V have been extracted using the ($^3$He,$αγ$) and ($^3$He,$^3$He$^{\prime} γ$) reactions, respectively. From the level densities, microcanonical entropies are deduced. The high $γ$-energy part of the RSF is described by the giant electric dipole resonance. A significant enhancement over the predicted strength in the region of $E_γ \lesssim 3$ MeV is seen, which at present has no theoretical explanation.
