N2 - We have measured the total and differential cross-sections for coherently photoproduced ρ{variant}, ω and ρ{variant}′ on deuterium at 7.5 GeV. Using VDM relations, we have obtained γω2/γρ{variant}2 = 7.1 ± 1.5, σT(ρ{variant}d) = (54 ± 2) mb and σT(ωd) = (56 ± 5) mb. Assuming the amplitude for ρ{variant}′ production via an intermediate ρ{variant}0 to be small and that the amplitudes for ρ{variant}p and ρ{variant}′p elastic scattering are comparable, we found γρ{variant}′2/γρ{variant}2 = 6.0 ± 1.2 and σT(ρ{variant}′d) = (47 ± 6) mb.
