PROTON DRIP-LINE NUCLEI IN RELATIVISTIC MEAN-HELD THEORY

The position of the two-proton drip line has been calculated for even- even nuclei with 10 less than or equal to Z less than or equal to 82 i n the framework of the relativistic mean-field (RMF) theory. The curre nt model uses the NL3 effective interaction in the mean-field Lagrangi an and describes pairing correlations in the Bardeen-Cooper-Schrieffer (BCS) formalism. The predictions of the RMF theory are compared with those of the Hartree-Fock+BCS approach (with effective force Skyrme SI II) and the finite-range droplet model (FRDM) and with the available e xperimental information.
