The two-neutron Halo of 19-Boronhas been investigated within this work. This investigation used the Microscopic Cluster Model (MCM). The main properties of Halo nuclei such as binding energy, radius, and deformation of the core have been calculated in this study. The 19B has been defined in the shape of core-n-n. The 17B is the core of the system. The feature of the three-body system depended on a structure and a deformation of the core. The core of 17B hasn't been considered as an inert core but has some degree of freedom. This degree has a high influence on the structure of a three-body system. So we used the Microscopic Cluster Model (MCM). The main aim of this study is to expand using cluster model in a new version which is Microscopic Cluster Model.
