The production of charmonium states, $ chi sb1$ and $ chi sb2$, was measured at 300 GeV/c with $ pi sp+$, $ pi sp-$, and proton beams on a lithium target. The cross-sections were determined by analyzing the full data sample recorded, during the 1987-1988 running period, by experiment E705 at Fermilab. The $ chi$ mesons were detected through their radiative decay into J/$ psi$ $ gamma$ and the subsequent decay, $ psi to mu sp+ mu sp-$. / The measured cross-sections for the $ chi$ mesons and estimates of the cross section for direct production of J/$ psi$'s have been compared with measurements obtained in other experiments and with theoretical predictions within the framework of Quantum ChromoDynamics.
