Remarks on "Calculation of the quarkonium spectrum and $m_{b}$, $m_{c}$ to order $\alpha_{s}^{4}$"
In a recent paper, we included two-loop, relativistic one-loop, and second-order relativistic tree level corrections, plus leading nonperturbative contributions, to obtain a calculation of the lower states in the heavy quarkonium spectrum correct up to, and including, O( alpha /sub s//sup 4/) and le...
