摘 要: 在多维球坐标体系中 ,我们对施主为束缚离子激子用二维方法求解薛定谔方程。研究表明 ,该方法对于半定量分析简便易行 ,并获得了一个重要的质量比σc=0 .5 12。 With hyperspherical coordinates, we have proposed a simple procedure to solve the Schr*idinger equation for excitons bound to an ioned donor in two dimensions, which is accurate enough for a semi-quantitative analysis. We have obtained a critical mass ratio σ c=0.512 for the stability of the system. Mass dependence of eigenenergies in the low-lying states have been investigated.
