Lambda-nucleon effective interaction in unitary-model-operator approach Original Research Article

A lambda-nucleon effective interaction for lambda hypernuclei is derived in the unitary-model-operator approach. Numerical calculation is performed for Λ17O, using the hyperon-nucleon interactions of the Nijmegen soft-core including the ʹ97-models, Jülich à and B̃. The single-particle energies of lambda in the View the MathML source, View the MathML source, View the MathML source and the partial-wave contributions to the potential energy of lambda in the View the MathML source state are calculated.
