Abstract
A formalism is developed for the partial-wave analysis of data on meson photoproduction off deuterons and applied to photoproduction of eta and pi(0) mesons. Different interpretations of a dip-bump structure of the eta photoproduction cross-section in the 1670MeV region are presented and discussed. Helicity amplitudes for two low-mass S-11 states are determined.
