Pygmy dipole resonance in stable Ca isotopes
Pygmy dipole resonance in stable Ca isotopes
The properties of the low-lying electric dipole strength in the stable Ca-40 Ca-44 and Ca-41 isotopes have been calculated within the Extended Theory of Finite Fermi Systems (ETFFS). This approach is based on the random phase approximation (RPA) and includes the single-particle continuum as well as...

The properties of the low-lying electric dipole strength in the stable Ca-40 Ca-44 and Ca-41 isotopes have been calculated within the Extended Theory of Finite Fermi Systems (ETFFS). This approach is based on the random phase approximation (RPA) and includes the single-particle continuum as well as the coupling to low-lying collective states which are considered in a consistent microscopic way. For Ca-44 we also include pairing correlations. A good agreement with the existing experimental data for the gross properties of the low-lying strength has been obtained. We conclude that for the detailed understanding of the low-lying dipole strength an approach like the present one is absolutely necessary. |
