Abstract

Events in which the charmonium states

\frac{J}{ψ}

and

ψ^{'}

are produced in 225-GeV/c

π^{-}

Be collisions have been selected with a dimuon trigger. Coincidences with detected photons have identified radiative decays from the charmonium

P

states (

χ

) to the

\frac{J}{ψ}

. The fraction of

\frac{J}{ψ}

's resulting from such decays is determined to be 0.37±0.09.
