A three-body model proposed earlier (S. Kumar and V. S. Bhasin, Phys. Rev.C65, 034007 (2002)) to set up the wave function of 11 Li is extended to investigate structural properties of 11 Li like matter radius, momentum distributions of the halo neutrons and the core(c), and n–n and n–c correlations. The energies and widths of experimentally observed resonant states of 11 Li in continuum have been calculated by employing the complex scaling method. The model is further extended to study the β-decay of 11 Li to the decay modes: (i) deuteron + 9 Li channel and (ii) 11 Be * (18.3 MeV) state. The results obtained are found to be in reasonably good agreement with the experimental data.

The 3α resonant states of 12 C are investigated by taking into account the correct boundary condition for three-body resonant states. In order to show how the 3α resonant states having complex eigenvalues contribute to the real energy, we calculated the Continuum Level Density in the Complex Scaling Method.

We consider the evolution of the neutron-nucleus scattering length for the lightest nuclei. We show that, when increasing the number of neutrons in the target nucleus, the strong Pauli repulsion is weakened and the balance with the attractive nucleon-nucleon interaction results into a resonant virtual state in ^{18}18B. We describe ^{19}19B in terms of a ^{17}17B-nn-nn three-body system where the two-body subsystems ^{17}17B-nn and nn-nn are unbound (virtual) states close to the unitary limit. The energy of ^{19}19B ground state is well reproduced and two low-lying resonances are predicted. Their eventual link with the Efimov physics is discussed. This model can be extended to describe the recently discovered resonant states in ^{20,21}20,21B.
