The differential angle distribution of cross sections \begin{document}${\rm d}\sigma/{\rm d}{\rm cos}\theta$\end{document} is given. We also discuss the uncertainties of cross sections caused by the varying quark masses and the renormalization scale μ. We show that significant numbers of events for pairs of higher excited state quarkonia can be generated at the super Z factory."> Production of higher excited quarkonium pair at the super <i>Z</i> factory -
