The yield of {ital J}/{psi} and {psi}{prime} vector-meson states has been measured for 800-GeV protons incident on deuterium, carbon, calcium, iron, and tungsten targets. A depletion of the yield per nucleon from heavy nuclei is observed for both {ital J}/{psi} and {psi}{prime} production. This depletion exhibits a strong dependence on {ital x}{sub {ital F}} and {ital p}{sub {ital t}}. Within experimental errors the depletion is the same for the {ital J}/{psi} and the {psi}{prime}.
