英文摘要: Ground state systemic, properties of single-Lambda and double-Lambda hypernuclei for even-N Ca isotopes ranging from the proton drip-line to the neutron drip-line are studied by using the relativistic continuum Hartree-Bogoliubov theory with a density-dependent delta pairing interaction. Compared with the ordinary nuclei, the predicted neutron drip line nuclei are (77)(Lambda) Ca and Ca-78(LambdaLambda) respectively, i.e., the last bound hypernuclei has two more neutrons than that of ordinary nuclei. Based on the analysis of two neutron separation energies, neutron single particle energy levels, the contribution of continuum and nucleon-density distribution, giant halo phenomena due to pairing correlation and the contribution from the continuum are suggested to exist in Ca hypernuclei.
