Photoproduction of $\hat{I}\cdot$ mesons off neutrons from a deuteron target

Abstract

A formalism is developed for the partial wave analysis of data on meson photoproduction off deuterons and applied to photoproduction of $\hat{I}\cdot$ and $\ddot{I}{€}^0$ mesons. Different interpretations of a dip-bump structure of the $\hat{I}\cdot$ photoproduction cross section in the 1670 MeV region are presented and discussed. Helicity amplitudes for two low-mass $S_{11}$ states are determined.
