 TITLE=/ENERGY DEPENDENCE OF PION PRODUCTION BY PROTONS ON NUCLEI/;
 PURPOSE=/IF THE PROTON INDUCED POIN PRODUCTION PROCESS CAN BE
          SUFFICIENTLY WELL UNDERSTOOD, THE REACTION MIGHT CONSTITUTE A 
          USEFUL SPECTROSCOPIC TOOL FOR INVESTIGATION OF THE
          HIGH-MOMENTUM COMPONENTS OF NUCLEAR WAVE FUNCTIONS. THE
          PRESENT WORK WAS MOTIVATED BY THE EXPECTATION THAT A THROUGH
          INVESTIGATION OF THE ENERGY DEPENDENCE OF THE CROSS SECTIONS
          FOR A FEW FINAL STATES AS THE THRESHOLD ENERGY IS APPROACHED
          WOULD BE OF SUBSTANTIAL BENEFIT IN DETERMINING A PROPER
          DESCRIPTION FOR THE PRODUCTION PROCESS./;
