E1 STRENGTH IN LIGHT NUCLEI: SKYRME RPA ANALYSIS

Original language description

The giant dipole resonance (GDR) in N = 28 isotones (Ca-48, Ti-50, Cr-52, Fe-54) is analyzed in the framework of the Skyrme random-phase-approximation (RPA). Three Skyrme forces, SkM*, SLy6 and SV-bas, are used. The effects beyond RPA are simulated by the double folding procedure. We show that dipole strength exhibits a large collective shift, which testifies to a strong impact of the residual interaction and signals on considerable anharmonic effects. In Cr-52, a significant pairing impact is found. For exception of Ti-50, an acceptable agreement with the experiment data is obtained, which justifies the ability of Skyrme forces, to describe GDR in light nuclei.
