Abstract
A dripline nucleus C is studied in a Borromean three-body model of C++. The valence neutrons, interacting via a realistic potential, are constrained to be orthogonal to the occupied orbits in C. We obtain ample results supporting that C is an ideal -wave two-neutron halo nucleus: The ground state is bound by 390-570 keV, the root mean square neutron and proton radii are 4.0 and 2.4 fm, and the two neutrons are predominantly in orbits. The binding mechanism of C is discussed. One- and two-body density distributions elucidate the halo character as well as the correlated motion of the neutrons. The reaction cross sections of C+C collisions are predicted.
