Abstract：
The heavy quarkonium spectra were discussed with a confinement potential of the form V _c(r)=1/2kr ²+λr ⁴by using the Hypervirial Pade Approach. With choice of suitable parameters, we calculated the binding energy levels of cc and bb systems which provide good agreement with the experimental values.
