Neutron and proton driplines of single-Λ and double-Λ hypernuclei, Ξ- hypernuclei as well as normal nuclei are studied within a relativistic mean field approach using an extended form of the FSU Gold Lagrangian density. Hyperons are found to produce bound nuclei beyond the normal nuclear driplines. Radii are found to decrease in hypernuclei near the driplines, in line with observations in light Λ hypernuclei near the stability valley. The inclusion of a Ξ- introduces a much larger change in radii than one or more Λ's. © 2013 World Scientific Publishing Company.

Shapes of light normal nuclei and Λ-hypernuclei are investigated using the relativistic mean-field approach. The FSUGold parametrization is used for this purpose. The addition of a Λ is found to change the shape of the energy surface towards positive deformation, i.e., prolate shape. The deformation in a Λ-hypernucleus, when the hyperon is in the first excited state, is also discussed. The effect of the inclusion of the hyperon on the nuclear radius is generally small with one exception. © Società Italiana di Fisica / Springer-Verlag 2014.

Quadrupole deformation in Î›-hypernuclei

Shapes of light normal nuclei and -hypernuclei are investigated using the relativistic mean-field approach. The FSUGold parametrization is used for this purpose.
