Abstract

Exact m1 and approximate m−1 RPA sum rules have been calculated for most general Skyrme-type effective forces in both light and heavy spherical nuclei. The Goldhaber-Teller and liquid drop (or droplet) ansätze for m−1 are discussed. The corresponding results are compared with available experimental data and RPA results.

      This strength has been classified as “Pygmy” resonance, since its size is much smaller than the IVGDR one, in general few percents of the total sum rule for isovector dipole electric transitions. An overview of the experimental data and methods, up to the year 2012, can be found in Ref. [51]. In heavy asymmetric nuclei a neutron skin appears, i.e. a neutron radius substantially larger than the proton one.
