The 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 18C and 20C. In such a three-body framework, 20C has a bound subsystem (19C), whereas 22C has a Borromean structure with all subsystems unbound. 22C 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.

The structure nucleus [Formula: see text] is investigated in the Microscopic Cluster Model, using three-body model [Formula: see text]. This model is used to investigate neutron halo features such as binding energy of neutron valence, root-mean-square (rms) of radius and core deformation. All the features are studied in configuration-T and -Y. In this study, theoretical framework is used in the MATLAB software to run the computational calculations. The results are compared with the experimental data.

Recently, the energy spectrum of \boldsymbol{^{10}}10Li was measured upto \boldsymbol{4.6}4.6 MeV, via one-neutron transfer reaction \boldsymbol{d(^{9}\textrm{Li},~p)^{10}\textrm{Li}}𝐝(9Li,𝐩)10Li. Considering the ambiguities on the \boldsymbol{^{10}}10Li continuum spectrum with reference to new data, we report the configuration mixing in the ground state of the two-neutron halo nucleus \boldsymbol{^{11}}11Li for two different choices of the \boldsymbol{^{9}{\textrm{Li}}+n}9Li+𝐧 potential. For the present study, we employ a three-body (\boldsymbol{\textrm{core}+n+n}core+𝐧+𝐧) structure model developed for describing the two-neutron halo system by explicit coupling of unbound continuum states of the subsystem (\boldsymbol{\textrm{core}+n}core+𝐧), and discuss the two-neutron correlations in the ground state of \boldsymbol{^{11}}11Li.

Using a three-body model with density-dependent contact interaction, we discuss the role of dineutron correlation in the ground state properties as well as in the dipole excitation of typical weakly-bound Borromean nuclei, 11 Li and 6 He . We show that, while both the nuclei manifest themselves similar strong dineutron correlations to each other in the ground state, the energy distributions for the two emitted neutrons from the dipole excitation are considerably different. We also discuss briefly the diproton correlation in a proton-rich Borromean nucleus, 17 Ne .

The β-decay process of the 11 Li halo nucleus into 9 Li and d is reanalyzed within a three-body model. The 11 Li nucleus is described as a 9 Li +n+n system in hyperspherical coordinates. The transition probability per time and energy units measured in a recent experiment can be reproduced with a broad resonance located around 0.8 MeV and a weak absorption from the 9 Li + d final channel.
