摘　　要：从伸缩子—胶子有效耦合理论得到的重夸克势(Dilaton)势出发,计算了重介子的轻子衰变和辐射跃迁宽度,并与Cornell势所得到的相应结果作了比较.结果表明,Dilaton势的计算结果比Cornell势的相应结果更好地符合实验数据.Using the potential which emerges from the effective dilaton-gluon coupling, the widths of the leptonic decay and radiative transition are calculated for J/Ψ and Υ families and compared with that of the Cornell potential. The better results are obtained with respective to the Cornell potential.
