Abstract：
Starting from the QCD potential which emerges from the effective dilaton gluon coupling,the energy levels and the widths of the leptonic decay and radiative transition are calculated for heavy mesons(c and b)and compared with that of the Cornell potenial.The better results are obtained with respective to the Cornell potential.The dilaton mass is estimated to be 57MeV.
