Abstract
The extended Skyrme interaction involving additional momentum- and density-dependent terms is adopted to uniformly describe the properties of nuclear matter and finite nuclei, as well as the nuclear reaction properties. A new set of extended Skyrme interaction parameters is constructed by simultaneously fitting the properties of nuclear matter and the experimental data of finite nuclei and neutron-nucleus scattering observables. These data include the binding energies and charge rms radii of some spherical even-even nuclei, the total cross sections, nonelastic cross sections, elastic-scattering angular distributions, and analyzing powers. Compared with the existing Skyrme interactions, the obtained extended Skyrme interaction has a significantly improvement in the agreement with corresponding experimental data, together with some additional constraints on nuclear matter.
