Recent relativistic mean field calculations by Schaffner et al. predict the existence of a broad class of multiply strange nuclei, composed of neutrons, protons, Λ's and Ξ's, with density ρ≈2ρ0, strangeness fraction ¦S¦/A≈1 and charge fraction q/A≈0, comparable to the properties of hypothesized strange quark matter. These features are well reproduced by a generalized Bethe-Weizsäcker mass formula which is used here to derive strong-decay stability regions and weak-decay patterns for multi-strange baryonic nuclei.
