The yield of J/ and 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 J/ and production. This depletion exhibits a strong dependence on xF and pt. Within experimental errors the depletion is the same for the J/ and the.
