Inclusive gamma-ray spectra from psi/3095/ and psi-prime/3684/ decays

Inclusive ..gamma..-ray spectra from psi (3095) and psi' (3684) decays have been observed with segmented arrays of NaI(Tl) in an e/sup +/e/sup -/ colliding-beam experiment. Three major peaks are seen in the psi' spectrum corresponding to psi' ..-->.. chi..gamma.. with m/sub x/ = 3561, 3511, and 3413 MeV/c/sup 2/ and with branching fractions of (7.0 +- 2.0), (7.1 +- 1.9), and (7.2 +- 2.3) %, respectively. Enhancements in the psi' spectrum at higher energies are consistent with decays chi ..-->.. psi..gamma... The psi spectrum shows no statistically significant structure.
