摘要：

We have studied the inclusive photon spectrum in psi(2S) decays using the CLEO III detector. We present the most precise measurements of electric dipole (E1) photon transition rates for psi(2S)-->gammachi(cJ)(1P) (J=0,1,2). We also confirm the hindered magnetic dipole (M1) transition, psi(2S)-->gammaeta(c)(1S). However, the direct M1 transition psi(2S)-->gammaeta(c)(2S) observed by the Crystal Ball as a narrow peak at a photon energy of 91 MeV is not found in our data.
