An experiment performed at Fermilab used double-arm calorimeter triggers to study di-jet production by 400 GeV protons and 200 GeV π- mesons incident on liquid hydrogen. The observed ratio of positive to negative leading particles in the jets was compared for pp and πp production using a tree level parton scattering model. The results are moderately sensitive to the form of the pion gluon distribution function and yield cc 9(x) ≃ (1-X) 2.75±0.40±0.75.
