Arguments of whether this value can be reduced due to screening effects are discussed. A density dependent delta interaction with cutoff is adjusted so as to approximately reproduce the nuclear matter values with the Paris force. ©2001 American Physical SocietyThis work was supported in part by DGESIC (Spain) under Contract No. PB98-0676, by the Groupement de Recherche: Noyaux Exotiques, CNRS-IN2P3, and by the programs Estancias de cientıíicos y tecnólogos extranjeros en España, SGR98-11 (Generalitat de Catalunya), and DGICYT (Spain) No. PB98-1247.Peer Reviewe
