High-Energy Photoproduction ofρ0Mesons from Hydrogen and Deuterium

Abstract

We have measured the photoproduction of ${\rho }^0$ mesons from hydrogen and deuterium as a function of the photon energy, $k_{\gamma }$, and the square of the momentum transfer, $t$. The assumption that the $\rho$ is produced by a purely diffractive mechanism is midly contradicted by the data.
