Abstract
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 and resonances (e.g., , and , , respectively). The calculations in general are sensitive to the value of the well-width parameter . Good agreement with experiment is obtained for decays of low-lying states (such as and ) and for the decay . The calculated width for the decay is less than that predicted by Kunzst et al., on the basis of a phenomenological Lagrangian by a factor of 3 or more.
