Photoproduction ofωMesons from Hydrogen and Deuterium

Abstract
ω-meson photoproduction cross sections, summed over elastic (γNωN) and inelastic (γNωN*) channels, have been measured from hydrogen and deuterium targets. The results agree with a calculation which includes only elastic and N*(1236) channels, suggesting that photoproduction of higher resonances is small. No evidence is found for I=1 natural-parity (e.g., A2) exchange.
