Description

Results from the Crystal Ball experiment at SPEAR are presented. A preliminary analysis of the 3 photon final state from the J/psi(3095) and of the cascade decays of the psi'(3684) yield new upper limits on the controversial states X(2820), chi(3455) and the even C-parity state at 3.59 GeV. From inclusive γ-ray spectra of the J/psi and psi' preliminary branching ratios for psi → chi states and upper limits for J/psi, psi' → etasub(c), eta'sub(c) are given. (orig.)
