| Abstract: | The formation mechanism for the octahedral central structure of the He7+ cluster is proposed and its totalenergy curve is calculated by the method of a modified arrangement channel quantum mechanics (MACQM). The energyis a function of separation R between two nuclei at the center and an apex of the octahedral central structure. The resultof the calculation shows that the curve has a minimal energy -19.7296 a.u. At R = 2.40 α0. The binding energy of He7+with respect to He+ +6He was calculated to be 0.6437 a.u. This means that the cluster of He7+ may be formed in thestable octahedral central structure with R = 2.40 α0. |
