HARTREE-FOCK CALCULATION OF HELIUM HYPERNUCLEAR BINDING ENERGIES

The binding energies of the s-shell hypernuclei (H4Λ, He5Λ, and He6ΛΛ) have been calculated in the Hartree-Fock model, using Gaussian particle-particle potentials. Parameters of the Λ-N interaction were determined from the experimental binding energies. These numerical results agree qualitatively with those of other calculations and also with the experimental Λ-N scattering data, if short-range repulsions are included. Equality of the Λ-N and Λ-Λ potentials is consistent with these calculations. © 1969 The American Physical Society.
