Abstract: In an analysis of the $\gamma \gamma \mu^+ \mu^-$ final state observed in $\psi´$ decays we investigate the radiative cascade transitions $\psi´ \to \gamma P_{c/\chi} \to \gamma \gamma J/\psi$ and the decays $\psi \to \eta J/\psi, \pi^{\circ}J/\psi$. Furthermore, the decay sequences $\psi \to \gamma\chi \to \gamma\pi^+\pi^-, \gamma K^+K^-$ are observed in a study of hadron pairs from $\psi´$decays. Decay branching ratios (or limits on them) are presented and compared to those from other experiments.
