We present measurements of ψ production and subsequent dimuon decay from 400-GeV/c proton interactions in an iron target over a range of Pt from 0 to 4 GeV/c and xF from - 0.25 to 0.40. The best fits give Edσ/dxF∝(1-|xF|)2.96±0.27 and dσ/dPt2∝exp(-2.23±0.05Pt) for Pt>1.2 GeV/c. The observed values of Bdσ/dy|y=0 and Bσ are 14.0±2.9 and 22.9±4.7 nb/nucleon, respectively.
