Description
We study the change in nuclear deformation induced by the presence of one or two lambda hyperons in light medium-heavy nuclei, comparing Skyrme-Hartree-Fock and relativistic mean field model predictions. The physical origin of the deformation changes is discussed in terms of the lambda and nucleon mean field potentials. We identify 30Si and 30S as candidates with possible large deformation differences between the core nucleus and hypernucleus. (author)
