| 摘 要： | The formation mechanism for the icosahedral central structure of the He13^ cluster is proposed and its total energy curve is calculated by the method of a Modified Arrangement Channel Quantum Mechanics. 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 He13^ with respect to He^ 12He was calculated to be 1.4046 a.u. This means that the cluster of He13^ may be formed in an icosahedral central structure with strong binding energy.

| Abstract: | The formation mechanism for the icosahedral central structure of the He13+ cluster is proposed and itstotal energy curve is calculated by the method of a Modified ArrangementChannel Quantum Mechanics. The energy is the function of separationR between two nuclei at the center and an apex of the icosahedral centralstructure. The result of the calculation has shown that the curve has aminimal energy -37.5765 (a.u.) at R=2.70a0. The bindingenergy of He13+ with respect to He+ +12He was calculated to be 1.4046 a.u. This means that the cluster ofHe13+ may be formed in an icosahedral central structurewith strong binding energy. |
