Self-consistent calculations of hypernuclear properties with the Skyrme interaction

An extension of the Skyrme--Hartree--Fock formalism is proposed for calculating Λ binding energies (B/sub Λ/) in hypernuclei throughout the periodic table. The calculation includes the self-consistent nuclear polarization by the Λ hyperon. Realistic estimates for ground state B/sub Λ/'s are obtained with a simple effective ΛN force and are compared with a Λ--nucleus potential model. The Λ particle excitation spectra have also been calculated. They are discussed in the context of strangeness analog state formation, and the emphasis is put on the symmetry between Λ and nuclear states
