Abstract

We present a self consistent Skyrme-Hartree-Fock calculation of the binding energies ofΛ-hypernuclear states experimentally determined by (π+,K +) reactions. A Skyrme type parametrization of theΛ-N interaction is derived, including two and three body terms, The importance of each of these terms is discussed. An overall agreement is reached even for deeply boundΛ states. The binding energies of thes- andp-shell hypernuclei are also well reproduced. No signal of quark deconfinement has been found. We conclude that the shell model picture works very well to describe deeply bound states for heavyΛ hypernuclei.
