Abstract

A formalism is developed for the partial wave analysis of data on meson photoproduction off deuterons and applied to photoproduction of η and π⁰ mesons. Different interpretations of a dip-bump structure of the η photoproduction cross section in the 1670 MeV region are presented and discussed. Helicity amplitudes for two low-mass S₁₁ states are determined.
