Singapore: World Scientific Publ Co Pte Ltd, v. 20, p. 254-262, 2011.0218-3013http://hdl.handle.net/11449/24292The general properties of exotic carbon systems, considered as a core with a two-neutron (n - n) halo, are described within a renormalized zero-range three-body model. In particular, it is addressed the cases with a core of (18)C and (20)C. In such a three-body framework, (20)C has a bound subsystem ((19)C), whereas (22)C has a Borromean structure with all subsystems unbound. (22)C is also known as the heaviest:, carbon halo nucleus discovered. The spatial distributions of such weakly-bound three-body systems are studied in terms of a universal scaling function, which depends on the mass ratio of the particles, as well as on the nature of the subsystems.254-262engHalo nucleiBinding EnergiesFaddeev EquationThree-body SystemsArtigo10.1142/S0218301311040335WOS:000298820900034Acesso restrito37406397265453158621258845956348
