Abstract

The nuclear physics group at the Oslo Cyclotron Laboratory has developed a method to extract nuclear level density and γ‐ray strength function from first‐generation γ‐ray spectra. This method is applied on the nuclei 44,45Sc and 50,51V in this work. The experimental level densities of 44,45Sc are compared to calculated level densities using a microscopic model based on BCS quasiparticles within the Nilsson level scheme. The γ‐ray strength functions are also compared to theoretical expectations, showing an unexpected enhancement of the γ‐ray strength for low γ energies (Eγ⩽3 MeV) in all the isotopes studied here. The physical origin of this enhancement is not yet understood.
