The energy is thefunction of separation R between the nuclei at the center and an apex of the body-centered cubic structure. The resultof the calculation shows that the curve has a minimal energy -25.6669 (a.u.) at R -- 2.550ao. The binding energy ofHe+ with respect to He^++8He was calculated to be 0.8857 a.u. This means that the cluster of He^+9 may be formed inthe body-centered cubic structure of R=2.55ao.展开更多

The ene...The formation mechanism for the octahedral central structure of the He7^+ 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 minimM energy -19.7296 a.u. at R = 2.40α0. The binding energy of He7^+ with respect to He^+ +6He was calculated to be 0.6437 a.u. This means that the duster of He7^+ may be formed in the stable octahedral central structure with R=2.40 α0.展开更多

The energy is the function of separation R between two nuclei at the center and an apex of the icosahedral central structure. The result of the calculation has shown that the curve has a minimal energy -37.5765 (a.u.) at R = 2.70ao. The binding energy of He+13 with respect to He+ + 12He was calculated to be 1.4046 a.u. This means that the cluster of He+13 may be formed in an icosahedral central structure with strong binding energy.展开更多
