摘　　要：本文是在我们前一篇文章工作的基础上,考虑与自旋有关的位势,从而算出能谱的精细结构。然后,再将我们在前一篇文章所得到的能级表达式与由WKB近似法所推出的S波的原点波函数的模方表达式结合起来,求出轻子衰变宽度。结果表明,大多数理论计算值与实验结果相符合。This report is based on our previous work and taking the account of spin dependent potential, the fine structure of energy levels was hence calculated. Further more, by the energy level formula obtained in the previous paper and the module square of S—wave zero point wave function formula from WKB approximation method, we evaluating the leptonic decay widths of heavy quarkonium. It manifest that the majority theoretical calculated results were in satisfactory agreement with experimental values.
