摘要
For coherent photoproduction of phi and omega mesons from deuteron at forward angles, the isovector pi-exchange amplitude is strongly suppressed. We show a possibility to study the nondiffractive channels associated with the unnatural parity exchange in phi photoproduction and with the baryon resonance excitations in omega photoproduction by measuring the spin observables.
