Shift of the Proton Drip Line by Λ-Hyperons

Addition of a Λ-hyperon to non-strange nuclei can lead to an increase in the binding energy and formation of a bound hypernucleus with an unbound nucleon core, effectively leading to the shift of the proton drip line on the hypernuclear chart. The structure of light proton-rich Λ-hypernuclei with 5 ≤ Z ≤ 12 is treated within the Hartree–Fock approach with effective potentials in the Skyrme form. We show that nuclei 8 C and 16 F are most likely can be bound by a hyperon.
