Abstract
A simplified phenomenological analysis of the Λ binding energies for the p-shell hypernuclei is given on the basis of the shell-model configuration [(1s)N4(1p)NA-5(1s)Λ], using the intermediate-coupling formalism set up in Part I, assuming the ΛNN interaction Q000 of central form (as motivated by the double-OPE mechanism), and taking into account the new data recently available about several p 1 2-shell hypernuclei. The systematics of the mass matrix for p-shell Λ hypernuclei are discussed in some detail. The fit obtained has only moderate strengths for the (ΛN) spin-orbit and (ΛNN) three-body interactions and requires rather little mixing of different nuclear core states into the hypernuclear wavefunctions, except for the special case Λ8Li. The implications of this fit are spelled out for the well-known hypernuclear species. A discrepancy between the wavefunction calculated here for Λ8Li and the characteristics of the decay Λ8Li → ααπ- is emphasized, as is also the need for Λ hypernuclear γ-ray data.
