Abstract

The deformations of light Λ hypernuclei are studied in an extended nonrelativistic deformed Skyrme-Hartree-Fock approach with realistic modern nucleonic Skyrme forces, pairing correlations, and a microscopical lambda-nucleon interaction derived from Brueckner-Hartree-Fock calculations. Compared to the large effect of an additional Λ particle on nuclear deformation in the light soft nuclei within relativistic mean field method, this effect is much smaller in the nonrelativistic mean-field approximation.
