摘要：

The Roper resonance photoexcitation amplitude is calculated by use of a quark model with a Lorentz scalar confining potential perturbed by a Coulomb-type vector potential. All the necessary complications due to SU(6) admixture, relativistic effects, and non-single-quark-transition interactions are considered. The result is found to be in good agreement with experiment. © 1979 The American Physical Society.
