氢分子离子的平衡距离随外磁场强度的变化

The Variation of Internuclear Equilibrium Separations of Hydrogen Molecular Ion in Strongly External Magnetic Field

考虑两核之间的相互作用,采用单中心展开方法,用B-splines基函数将氢分子离子的波函数在径向和角向同时展开,计算超强平行外磁场中氢分子离子的能级与磁场强度的关系,两核间的平衡距离随磁场变化规律.计算结果表明:磁量子数-m越大,R——γ曲线下降越快,氢分子离子越容易被压缩;磁场越强,塞曼能级也就越低,当磁场γ大于500时,R——γ曲线近似为直线。

Considering the interaction between two atomic nucleus in the hydrogen molecular ion, one-center expansion method and the B-splines basis function are used to build into the trial wave function and angular wave function of hydrogen molecular ion. The variation of energy levels and the internuclear equilibrium separations in hydrogen molecular ion are investigated in the altra-strong external parallel magnetic field. The calculation results in this paper show： the magnetic quantum number --rn is larger, the R-γ curves drop more quickly, and the hydrogen molecular ion is condensed more easily. In addition, the stronger the magnetic field, the lower the Zeeman energy levels. When the magnetic field γ 500, the curves R-- γ are straight lines approximately.
