Giant Neutron Halo in Exotic Calcium Nuclei
-
Abstract
The properties of even-even Ca isotopes are studied using the
relativistic continuum Hartree-Bogoliubov theory. The calculations reproduce very wwell the experimental binding energies E and two neutron separation energies S2n. The predicted neutron drip nuclei is 72Ca. From the analysis of S2n, the neutron radii and neutron density distribution, giant neutron haloes are predicted in Ca isotopes with A > 60. -
