 TITLE=/DIFFERENTIAL CROSS SECTION FOR PROTON-PROTON BREMSSTRAHLUNG AT
        1.38 GEV/C/;
 PURPOSE=/WE REPORT FINAL RESULTS AND THE EXPERIMENTAL DETAILS OF THE
          FIRST INVESTIGATION AT MEDIUM ENERGY OF PROTON-PROTON
          BREMSSTRAHLUNG(PPGAMMA) . THE INCIDENT PROTON ENERGY IS WELL
          ABOVE THE INELASTIC THRESHOLD IN PP INTERACTIONS AND IS
          SUBSTANTIALLY HIGHER THAN THE ENERGIES OF ALL PREVIOUS
          PPGAMMA EXPERIMENTS.  AN IMPORTANT OBJECTIVE OF OUR EXPERIMENT
          IS TO TEST THE RANGE OF VALIDITY OF THE SOFT PHOTON
          APPROXIMATION BASED ON THE LOW AND BURNETT-KROLL THEOREMS AND
          THAT OF THE EXTERNAL EMISSION DOMINANCE APPROXIMATION WHICH IS
          EQUIVALENT TO THE FIRST TERM OF THE SOFT PHOTON APPROXIMATION
          EXPANSION./;
