The formation mechanism for the icosahedral central structure of the He1 13 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 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.  相似文献

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.

选用类氧原子波函数,在单中心球模型近似下,利用变分法计算了H7^-团簇正八面体中心结构的能量曲线。结果表明,当中心H原子核能顶角H原子核之间的距离R=1.58a0时,体系能量有一极小值-4.0899453h.a.u.。这表明H7的正八面体中心结构是可能稳定存在的。计算结果与用MACQM法计算的结果基本相符,表明提出的物理模型及其计算方法是合理的。  相似文献

用类O原子波函数对H+9团簇的体心立方结构与能量的研究   总被引:5,自引:3,他引:2  
在单中心球模型近似下,选用类O原子解析函数,用变分法计算了H+9团簇体心立方结构与能量。结果表明当中心氢原子核到顶角氢原子核之间的距离R=1.97a0时,体系能量有一极小值E=-4.376h0(a0=0.529177×10-10m,h0=27.2eV)。这表明H+9团簇的体心立方结构是稳定的结构,H+9团簇是存在的。  相似文献

H^—5的正四面体中心和正方形中心构型能量的理论计算   总被引:2,自引:1,他引:1  
文中用MACQM(modifiedarangementchannelquantummechanics)方法计算了负离子团簇H-5的正四面体中心和正方形中心构型的能量随中心原子核到顶角原子核间距离R变化的曲线。计算得知,两种构型均在R=1.55a0时有能量极小值E正四面体中心=-2.7899a.u.,E正方形中心=-2.7539a.u.。说明H-5的这两种结构都可能存在,但正四面体中心结构较为稳定。  相似文献

选用类C原子波函数,在单中心球模型近似下,利用变分法计算了H-5团簇正四面体中心结构与能量。结果表明当中心H原子核到顶角H原子核之间的距离R=1.58a0时,体系能量有一极小值-2.8036h.a.u.。这表明H-5的正四面体中心结构是可能稳定存在的。计算结果与用MACQM法计算的结果基本相符,表明采用的物理模型及其计算方法是合理可靠的。  相似文献

本文提出了Li9团簇体心立方结构的形成机理,并对此结构的总能量随中心原子到顶点原子间核间距R的变化用芶氏改进的排列通道量子力学方法(MACQM)进行了计算。结果显示曲线在R = 4.77 a0处有一极小值 -67.160922 a.u.,这表明Li9团簇的体心立方结构是可能稳定存在的。在R趋于无穷大时这9个锂原子的总能量为 -66.852240 a.u.,所以形成Li9的总结合能为0.308682 a.u.。因此Li9 团簇的原子平均结合能是0.034298 a.u.或0.933 eV,它大于我们过去计算的Li5团簇正四面体中心结构的原子平均结合能0.632 eV、Li7 团簇正八面体中心结构的原子平均结合能0.674 eV和Li13 团簇正二十面体中心结构的原子平均结合能0.810 eV。故在体心正多面体结构Lin (n= 5 ,7,9,13)中,Li9的体心立方结构有最大的原子平均结合能,这也许是碱金属晶体的晶胞取体心立方结构的一个原因。  相似文献

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.  相似文献
