| Abstract: | A calculation for mass spectra and leptonic decay rates of heavy quakonia is given in a relativistic quark model,which includes full relativistic corrections to the quark-antiquark potential and the vector decay constants.Both the obtained mass spectra and leptonic decay rates agree well with the available experimental data. |

| Keywords: | heavy quarkonium mass spectrum leptonic decay rate relativistic quark model |
