摘要

Starting from the quasiparticle random phase approximation based on the Skyrme interaction SLy5, we study the effects of phonon-phonon coupling (PPC) on the low-energy electric dipole response in Ca40-58. Using the same set of parameters we describe available experimental data for Ca-40,Ca-44,Ca-48 and give the prediction for Ca50-58. The inclusion of the PPC results in the formation of low-energy 1(-) states. There is an impact of the PPC effect on low-energy E1 strength of Ca-40,Ca-44,Ca-48. The PPC effect on the electric dipole polarizability is discussed. We predict a strong increase of the summed E1 strength below 10 MeV, with increasing neutron number from Ca-48 until Ca-58.
