Abstract

Nucleus 19B and 22C are the neutron-rich nuclei which has a Borromean system (core + n + n). These two nuclei were placed near to neutron drip line which mean it not very stable and tended to release two valence nucleon (neutron). In this case these two nuclei had two-neutron halo that are weakly bound between the core and the two valence nucleon. According to the experimental data, these two nuclei had low three-body binding energy which are-1.14?MeV (19B) and-1.360?MeV (22C). In this paper, we used cluster microscopic model (three-body model+shell model) to investigate the structure of two-neutron halo 19B and 22C. We used s-and p-state (wavefunction) approach to study the core deformation parameter and the binding energy of the three-body. The results showed the binding energy of valance nucleon of 19B were-1.248,-1.570 and-1.670?MeV, meanwhile for 22C were-1.239,-1.661 and-1.777?MeV. These two nuclei exhibit prolate shapes due to the values of core deformation parameter were 0.400 and 0.5357 for 19B and for 22C were 0.3600 and 0.5261. In conclusion, 19B and 22C still experienced halo phenomena for both s-and p-states.
