Abstract

Within the framework of the vector-dominance model, a method for an experimental study of the energy dependence of the pion-vector-meson scattering amplitudes is proposed for the reaction γN → ΔV⁰π. The method is based on an analysis of the moments of the spherical harmonics of the γπ → V⁰π process. This analysis is attractive, in particular, in the case that s-channel helicity conservation can be assumed for the V⁰π scattering process where then all the moments 〈Y_i{dotless}^m 〉 with m ≠ 0 vanish.
