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-Weizs\"{a}cker 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.
