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,$\alpha \gamma$) and (${}^3$He,${}^3$He${}^{\prime }\gamma$) reactions, respectively. From the level densities, microcanonical entropies are deduced. The high $\gamma$-energy part of the RSF is described by the giant electric dipole resonance. A significant enhancement over the predicted strength in the region of $E_{\gamma }\lesssim 3$ MeV is seen, which at present has no theoretical explanation.
