摘要：

We suggest a unified description of baryon form factors in terms of a two-component model with an intrinsic q(3) structure and a meson qq cloud, parameterized in terms of vector mesons. We use this model to study the N - Delta form factors. The results are in excellent agreement with data. The N - Delta transition appears to be dominated by coupling to the p meson.
