Abstract :The microscopic cluster model approach has been performed to study the nuclear structure of the lightest and heaviest two-neutron halo nuclei, $^{6}$He and $^{22}$C, respectively. The matter radius and binding energy for the $^{6}$He and $^{22}$C nuclei are calculated and the effect of the core deformation insert ignore into journalissuearticles values($^{20}$C); on the properties of $^{22}$C nuclei is also discussed. Calculations have shown that the microscopic cluster model provides a good description of binding energy as well as matter radius in comparison to experimental data. The fittings of some parameters such as central potential depth insert ignore into journalissuearticles values(V$_{o});$, empirical constant insert ignore into journalissuearticles values(r$_{o});$, and surface diffuseness value insert ignore into journalissuearticles values(a); are discussed to find agreement in the results with the available experimental data. The exotic properties of two-neutron halo nuclides $^{6}$He and $^{22}$C such as weak binding energy, abnormal large matter radius, and Borromean system have been confirmed in the present work.
