The nuclear three-body system, with two halo neutrons very weakly coupled to a heavy core, is studied to investigate necessary conditions for the occurrence of Efimov states. Extending the analysis to the scattering sector, we find that these states evolve into Feshbach type resonances. This behaviour is very similar to the 20 C nucleus in which the occurrence of Efimov states evolving into...
A brief overview of the attempts carried out by us in recent years to study the structural properties of 2n-rich halo nuclei such as 14 Be, 19 B, 22 C, and 20 C in the light of Efimov effect is presented. In particular, the effect of occurrence of Efimov state in 20 C is analysed to show how it causes a resonance in n– 19 C scattering near scattering...
The discovery of neutron rich isotopes of the lightest elements on the neutron drip line exhibiting a halo structure has opened up new vistas in research activities. The novel structural features associated with the halo phenomena have been the subject for extensive theoretical and experimental investigations in recent times. In this talk, I propose to present a broad overview of the recent developments...
