  With accumulation of high statistics data at BES and CLEO-c, many new
interesting channels can get enough statistics for partial wave analysis (PWA).
Among them, $\psi \to \gamma p\bar p, \gamma\Lambda\bar \Lambda, \gamma\Sigma
\bar\Sigma, \gamma\Xi\bar \Xi$ channels provide a good place for studying
baryon-antibaryon interactions; the double radiative decays
$\psi\to\gamma\gamma V$ with $V\equiv \rho,\omega,\phi$ have a potential to
provide information on the flavor content of any meson resonances (R) with
positive charge parity ($C=+$) and mass above 1 GeV through $\psi\to\gamma R
\to\gamma\gamma V$; $\psi(2S)\to\gamma\chi_{c0,1,2}$ with $\chi_{c0,1,2}\to
K\bar K \pi^+\pi^- $ and $2\pi^+2\pi^-$ decays are good processes to study
$\chi_{cJ}$ charmonium decays. Using the covariant tensor formalism, here we
provide theoretical PWA formulae for these channels.
