Abstract

We have performed a systematic calculation of low-lying dipole responses for even-even nuclei, up to zirconium isotopes including deformed nuclei within the fully self-consistent random phase approximation using the Skyrme interaction. We found the low-lying peaks in the dipole strength, so-called the pygmy dipole resonance (PDR), in every isotopic chain. The E1 strength of the PDR strongly depends on the position of the neutron Fermi level and shows a clear correlation with the occupation of the orbits with low orbital angular momenta (low-l). We also found a strong correlation between the neutron skin thickness and the pygmy dipole strength in the region where the neutron Fermi levels are located at low-l orbits.
