We discuss angular distributions and polarization effects for e/sup -/e/sup +/..-->..V..--> gamma..X and e/sup -/e/sup +/..-->..V..-->..l/sup -/l/sup +/X, where V is a heavy quarkonium and X is a Higgs particle or a pseudo-Goldstone boson. The final-lepton angular distributions are sensitive to the parity of X. We investigate the systematics of various angular components in terms of the helicity formalism. We also give an estimate of the reaction rate. Our formalism can be applied to the case when the X is a spin-zero quarkonium state.
