By adding to the conventional form of Skyrme force a term with simultaneous momentum and density dependence it is possible to define a new force, labeled SkSP.1, that gives a good fit to the masses of 416 spherical (or near-spherical) nuclei in Hartree-Fock BCS calculations, while having the nuclear

## Generalized density dependence in Skyrme effective interactions is investigated to get forces valid beyond the mean field approximation. Preliminary results are presented for infinite symmetric and asymmetric nuclear matter up to pure neutron matter.
The HFB-2 mass formula is generalized to make the δ-function pairing force density-dependent. It is shown that the mass data rule out the simple model of a pairing force that vanishes completely in the nuclear interior. Consistency with the mass data is found for a fairly wide range of δ-function pa
The dependence of the fission barrier of 24°pu on the parameters of an effective interaction of the Skyrme type is examined in the Hartree-Fock + BCS model. The strong influence of the surface-symmetry properties on the average trend, and of the effective mass on the shell oscillation, are pointed o
