Abstract

The giant dipole resonance (GDR) in N = 28 isotones ( ⁴⁸Ca, ⁵⁰Ti, ⁵²Cr, ⁵⁴Fe) 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 ⁵²Cr, a significant pairing impact is found. For exception of ⁵⁰Ti, an acceptable agreement with the experiment data is obtained, which justifies the ability of Skyrme forces to describe GDR in light nuclei. © 2012 World Scientific Publishing Company.
