Book excerpt: We have studied the production of the J/? and associated particles using the E672/E706 spectrometer at Fermilab. Preliminary results are presented from the first run in 1987--1988 with 530 GeV/c p/? and ?/sup −/ beams on a variety of nuclear targets. The A-dependance of J/? production with /pi//sup /minus// beam was found to agree with an A/sup ?/ parametrization with /alpha/ = 0.85 /plus minus/ 0.06 for X/sub F/ > 0.1. We have found that (41 /plus minus/ 22)% of the J//psi/'s produced in the p//pi//sup +/ beam are consistent with the radiative decay /chi/ /yields/J//psi/+?. The future analysis goals of the experiment are also discussed. 10 refs., 9 figs.
