One- and two-photon decays of meson resonances are calculated in a quark-oscillator model using a nonrelativistic interaction Hamiltonian and vector dominance. Harmonic-oscillator wave functions are assumed for l=0 and l=1 resonances (e. g. , , and A₂, f, respectively). The calculations in general are sensitive to the value of the well-width parameter ^2. Good agreement with experiment is obtained for decays of low-lying states (such as ^0 and) and for the decay A₂^^+ (predicted) =0. 4-0. 6 MeV. The calculated width for the decay f (1260) is less than that predicted by Kunzst et al. , on the basis of a phenomenological Lagrangian by a factor of 3 or more.
