THESE RESULTS WILL BE HELPFULL TO DETERMINE WHETHER THE TRANSITION IN THE PROPERTIES OF NEUTRON-DEFICIENT PRODUCTS WITH A=80-140 FORMED IN THE INTERACTION OCCURS AT THE SAME ENERGY FOR ALL ISOBARIC NUCLIDES OR WHETHER IT OCCURS AT DIFFERENT ENERGIES DEPENDING ON THE COPOSITION OF THE PRODUCT. FURTHERMORE, IT IS NOT KNOWN WHETHER THE PEAK IN THE RATIO OF FORWARD-TO-BACKWARD EMISSION(F/B) IS ALSO FIRST SEEN FOR PRODUCTS OF THIS SAME COMPOSITION. RESULTS FOR ISOBARIC NEUTRON-DEFICIENT NUCLEIDES WOULD BE HELPFUL IN FILLING THE EXISTING GAPS./; ATH=(S.BISWAS'1',N.T.PORILE'1'); INST-ATH=(1USAPUR'1'); REF=PR/C; VLP=20(1979)1467; RCTS=(238U(P,X)131CE,238U(P,X)131LA,238U(P,X)131BA,238U(P,X)128BA, 238U(P,X)133BA,238U(P,X)135BA,238U(P,X)140BA); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,9; /*@54@*/ CHM=X; THK-TGT=20UM'3'; BAC=AL'3'; THK-BAC=20UM'3'; /*@55@*/ POL-TGT=NO; ALGN-TGT=NO; ACC=(SYNCYC'2',CYC'1'); /*@53@*/ INST-ACC=(1USAANL'1',1USALAM'2'); INC-ENGY-RANGE=(0.8GEV'2'); INC-ENGY-LAB-RANGE=1.0GEV(XMEV)11.5GEV'1'; BEAM-INTNSTY=XUA'4'; /*@56@*/ POL-PRJ=NO; DET-PARTCL=(GAMMA'5',X'6'); DET-SYS=(GE(LI)'5',X'6'); /*@57@*/ PHQ=(XSECTN'7',XSECTN-RATIO,LIFE,DECAY-GAMMA,BRANCH-RATIO); /*@59@*/ PHQ=(XSECTN,XSECTN-RATIO); /*@63@*/ RCT=238U(P,X)131CE'A'; RCT=238U(P,X)131LA'B'; RCT=238U(P,X)131BA'C'; RCT=238U(P,X)128BA'D'; RCT=238U(P,X)133BA'E,1'; /*@20@*/ RCT=238U(P,X)135BA'F,1'; /*@20@*/ RCT=238U(P,X)140BA'G'; ANL=(X'1'); /*@21@*/ PHQ=(X'2'); /*@22@*/ /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,9; /*@65@*/ /*FIG.4-(D)*/ /* D329 FIG.4-(D) */ /* SER#= 6 */ /* XSCALE=LOG YSCALE=LINEAR */ /* XMAX= 1.00000000E+01 YMAX= 9.99999642E-02 */ /* XMIN= 1.00000000E+00 YMIN= 1.99999996E-02 */ /* FOLLOWING DATA ARE TAKEN FROM GRAPH */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; INC-ENGY-LAB DATA'2,D' DELTA-DATA (GEV) (UNIT'3') (UNIT'3') 0.84 7.94E-02 6.02E-03 1.91 9.35E-02 5.59E-03 2.90 8.45E-02 5.16E-03 4.28 7.51E-02 6.45E-03 5.74 4.75E-02 5.59E-03 12.34 3.03E-02 5.16E-03 \END; /*===================================================================*/ |
