Λ single particle energies

The Λ single-particle energies BΛ of hypernuclei (HN) are calculated microscopically using the Fermi hypernetted chain method to obtain for our ΛN and ΛNN potentials the Λ binding D(ρ) to nuclear matter, and the effective mass m*Λ(ρ) at densities P≤ρ0 (ρ0 is normal nuclear density), and also the corresponding effective ΛN and ΛNN potentials. The Λ core-nucleus potential UΛ(r) is obtained by suitably folding these into the core density. The Schrödinger equation for UΛ and m*Λ is solved for BΛ. The fringing field (FF) due to the finite range of the effective potentials is theoretically required. We use a dispersive ΛNN potential but also include a phenomenological ρ dependence allowing for less repulsion for ρ<
