HOWEVER, THEIR CONTRIBUTION IS SIGNIFICANTLY LESS THAN IN THE (N,N) REACTION AT THE SAME EXCITATION ENERGY. IT IS AN URGENT PROBLEM OF NUCLEAR PHYSICS TO LEARN THE REASONS FOR THIS DIFFERENCE. FOR THIS PURPOSE IT IS NECESSARY FIRST OF ALL TO STUDY THE ABOVE MENTIONED OF THE (P,N) AND (N,N) REACTIONS OVER A RATHER WIDE ENERGY RANGE AND FOR AN EXTENSIVE NUMBER OF NUCLEI/; ATH=(G.N.LOVCHIKOVA'1',G.V.KOTELNIKOVA'1',O.A.SALNIKOV'1', YU.V.SOKOLOV'1',V.S.STAVINSKII'1',A.M.TRUFANOV'1',N.I.FETISOV'1'); INST-ATH=(4CCPFEI'1'); REF=SNP; VLP=27(1978)609; RCTS=(109AG(P,N)109CD); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,12; RCT=109AG(P,N)109CD; ENR=98.5%; CHM=ELM; THK-TGT=2.75MG/CM**2; BAC=SELF; POL-TGT=NO; ALGN-TGT=NO; ACC=(X'1'); /*@3@*/ INST-ACC=4CCPFEI; INC-ENGY-LAB-RANGE=(6MEV,7MEV); DELTA-INC-ENGY=XKEV; ERS-PRJ=XKEV; BEAM-INTNSTY=XUA; POL-PRJ=NO; DET-PARTCL=(GAMMA,N); DET-SYS=(X'1'); /*@4@*/ SOLID-ANGL=0.50DEG; ERS-DET=XKEV; ANL=(STATIST-MODEL); PHQ=(XSECTN,ANGL-DSTRN,ENGY-SPEC,LEVEL-DNSTY); /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,12; INC-ENGY-LAB=7MEV; ENGY-EMT-LAB=4.0[5.0MEV; /*FIG.2-(H)*/ /* D235 FIG 2-(H) */ /* SER#= 12 */ /* XSCALE=LINEAR YSCALE=LINEAR */ /* XMAX=-1.000E+00 YMAX= 6.000E+00 */ /* XMIN= 1.000E+00 YMIN= 4.000E+00 */ /* FOLLOWING DATA ARE TAKEN FROM GRAPH */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; COS-THTC DATA2'2' DELTA-DATA2 (NODIM) (NODIM) (NODIM) 0.87 5.89E+00 2.18E-01 0.70 5.85E+00 2.54E-01 0.49 5.53E+00 2.90E-01 0.24 5.45E+00 2.18E-01 -0.01 5.05E+00 2.18E-01 -0.50 5.75E+00 1.45E-01 -0.73 5.53E+00 2.18E-01 -0.87 5.82E+00 1.81E-01 \END; /*===================================================================*/ |
