Book Description
Results of studies of selected radiative decays of the psi' to charmonium and non-charmonium states which decay into photons are presented. These studies were performed using a sample of 1.8 x 106 produced psi''s collected by the Crystal Ball detector at the SPEAR electron-positron storage ring. The branching ratios of the chi0, chi2, and eta'/sub c/ to two photons have been measured to be (4.5 +- 2.2 +- 2.0) x 10−4, (9.5 +- 2.9 +- 4.5) x 10−4 (first errors statistical, second systematic), and 1 x 10−2 (90% C.L.). The signal from the decay chain psi' .--. .gamma.chi0, chi0 .-->. .pi.°.pi.° has been observed with essentially no background. Using the observed line shape of the radiative photon in this reaction, the full width of the psi0 has been found to be 8.8 +- 1.3 +- 1.5 MeV/c2. In addition, the branching ratios of the chi0 and chi2 to .pi.°.pi.° have been measured to be (3.5 +- 0.3 +- 1.2) x 10−3 and (1.2 +- 0.2 +- 0.4) x 10−3; the branching ratios of the chi0 and chi2 to eta eta have been measured to be (2.8 +- 0.9 +- 1.3) x 10−3 and (8.4 +- 4.2 +- 4.0) x 10−4. The decays of the psi' to four non-charmonium states have been investigated. The branching ratios and upper limits of these decays have been normalized to the branching ratios of the corresponding decays from the J/psi which have been measured using a sample of 2.2 x 106 produced J/psi's collected by the Crystal Ball detector. The ratios of the psi' branching ratios to the J/psi branching ratios for the final states .gamma.eta, .gamma.eta', .gamma.theta, and .gamma.f have been measured to be
