 TITLE=/ENERGY DEPENDENCE OF CHARGED PIONS PRODUCED AT 180 DEGREE IN
        0.8-4.89-GEV PROTON-NUCLEUS COLLISIONS/;
 PURPOSE=/(ABSTRACT) HIGH-ENERGY PIONS PRODUCED IN PROTON-NUCLEUS
          COLLISSIONS WAS STUDIED. BOTH THE SLOPES OF THE ENERGY
          SPECTRA AND THE PION-/PION+ RATIONS INCREASE RAPIDLY WITH
          PRIMARY ENERGY UP TO ABOUT 3-4 GEV, WHERE LIMITING VALUES
          APPEAR TO BE REACHED. THE DEPENDENCE ON TARGET MASS ALSO
          CHANGES OVER THIS ENERGY RANGE. UNLIKE FORWARD PION-PRODUCTION
          RESULTS, BACKWARD PIONS AT THESE ENERGIES DO NOT OBEY THE
          SCALING LAW BY SCHMIDT AND BLANKENBECLER./;
