We have studied the inclusive photon spectrum in psi(2S) decays using theCLEO III detector. We present the most precise measurements of electric dipole(E1) photon transition rates for psi(2S)--> gamma chicJ(1P) (J=0,1,2). We alsoconfirm the hindered magnetic dipole (M1) transition, psi(2S)-->gamma etac(1S).However, the direct M1 transition psi(2S)-->gamma etac(2S) observed by theCrystal Ball as a narrow peak at a photon energy of 91 MeV is not found in ourdata.
