Photoproduction of theψParticles

Abstract

The $s$ and $t$ dependence of incoherent $\psi \mathrm{}\left(3100\right)\mathrm{}$ photoproduction from deuterium has been measured at the Stanford Linear Accelerator Center. $\psi \mathrm{}\left(3700\right)\mathrm{}$ photoproduction and $\psi \mathrm{}\left(3100\right)\mathrm{}$ photoproduction from hydrogen have also been measured.
