| 摘 要： | 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.

| Abstract: | 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 minimal energy
-19.7296 a.u. at R=2.40a0. 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 the stable octahedral
central structure with R=2.40a0. |
