The cross sections of e{sup +}e{sup -} to S-wave and P-wave quarkonia with C-parity even associated with a photon are analyzed in the framework of nonrelativistic Quantum Chromodynamics (NRQCD) factorization formulism. The short-distance coefficients are analytically determined up to the next-to-leading order (NLO) QCD radiative corrections to S-wave and P-wave quarkonium production and NLO relativistic correction to {eta}{sub c} production. We also invoke the analytical expressions to estimate the cross sections. Our numerical results indicate that both the QCD and the relativistic corrections are considerable.
