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./; ATH=(L.S.SCHROEDER'1',S.A.CHESSIN'1',J.V.GEAGA'1',J.Y.GROSSIORD'1', J.W.HARRIS'1',D.L.HENDRIE'1',R.TREUHAFT'1',K.VAN BIBBER'1'); INST-ATH=(1USABRK'1'); REF=PRL; VLP=43(1979)1787; RCTS=(C(P,PIP,X), C(P,PIN,X), AL(P,PIP,X),AL(P,PIN,X),CU(P,PIP,X), CU(P,PIN,X),SN(P,PIP,X),SN(P,PIN,X),PB(P,PIP,X),PB(P,PIN,X)); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,1; ENR=NAT; CHM=ELM; ACC=(BEVATRON); INST-ACC=1USABRK; INC-ENGY-RANGE=(0.8GEV,1.05GEV,2.1GEV,3.5GEV,4.89GEV); BEAM-INTNSTY=10**10/PULSE; /*@3@*/ /*@8@*/ /*@4@*/ DET-PARTCL=(PIP,PIN); DET-SYS=(MAG+TOF+SCT,EDE); /*@2@*/ /*@5@*/ /*@6@*/ /*@7@*/ /*@13@*/ PHQ=(ENGY-SPEC,XSECTN-RATIO,SP-INCL-SPEC); RCT=CU(P,PIP,X); RCT=CU(P,PIP,X); /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,1; CMPD=X; RSD=X; /*@6@*/ /*FIG.1-(A)*/ /* D181 FIG 1-(A) */ /* SER#= 1 */ /* XSCALE=LINEAR YSCALE=LINEAR */ /* XMAX= 8.000E+00 YMAX= 6.000E+01 */ /* XMIN= 0.000E+00 YMIN= 0.000E+00 */ /* FOLLOWING DATA ARE TAKEN FROM GRAPH */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; INC-ENGY-LAB DATA1'9' DELTA-DATA1 (GEV) (MEV) (MEV) 0.77 3.63E+01 2.13E+00 1.04 4.16E+01 1.99E+00 2.08 5.29E+01 2.28E+00 3.50 5.79E+01 2.42E+00 4.87 6.26E+01 2.13E+00 \END; /*===================================================================*/ |
