Two-neutron drip lines of a few single lambda hypernuclei

Abstract Two-neutron drip lines of a few single lambda hypernuclei are studied through a phenomenological binding energy model. This model, which is built from the Bethe-Weizsäcker formula, explicitly takes into account hyperon mass and strangeness. For the hypernuclear isotopic chains of the elements C—Mn, the heaviest isotope in each chain that is stable with respect to two-neutron decay is located.
