The Formation Mechanism and Binding Energy for the Octahedral Central Structure of the Cluster

The formation mechanism for the octahedral central structure of the cluster is proposed and its total energy curve is calculated by the method of a modified arrangement channel quantum mechanics (MACQM). The energy is a function of separation R between two nuclei at the center and an apex of the octahedral central structure. The result of the calculation shows that the curve has a minimal energy -19.7296 a.u. at R=2.40a0. The binding energy of with respect to +6He was calculated to be 0.6437 a.u. This means that the cluster of may be formed in the stable octahedral central structure with R=2.40a0.
