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.

The two-neutron halo nucleus 11 Li has been investigated in this work. Jacobi coordinates is used to describe the three-body system, using two configurations that are the T-configuration and Y-configuration. The calculations have been calculated based on a cluster model. The 11 Li nucleus is considered as three-body system core (9 Li )+n+n. The core here has been considered as a deformed core. The calculations confirmed that the core has some deformation and has an oblate shape which in turn has effects on the structure of three-body system.

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.

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.

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.

The ([Formula: see text]Ne) nucleus is described as two protons outside of a deformed core. The Microscopic Cluster Model (MCM) is used to describe the three-body system [Formula: see text] with Jacobi coordinates. This model strongly exhibits the Coulomb effect and therefore it is used to explore the role of the Coulomb effect in proton halo formation. The main goal of this study is to confirm that [Formula: see text]Ne is a two-proton halo nucleus. In the calculations, the energy states (0[Formula: see text]), (1[Formula: see text]), (0[Formula: see text]) and (0[Formula: see text]) are considered to be occupied by two valence protons. Based on the comparison with other theoretical and experimental studies, the present MCM calculations show that the exotic structure of the valence protons is not evident in the halo structure of [Formula: see text]Ne.

This paper provides an overview of the experimental data on the 19C nucleus, which qualify its structure as a nucleus with a singleneutron halo. A theoretical approach (two-body cluster model) is described, which allows to take into account the specificity of the halo structure.
