THE MOST OBVIOUS EXPLANATION OF THIS FACT IS THAT AT A=131 THE TRANSITION BETWEEN THESE PROCESSES OCCURS BETWEEN Z=55 AND 57, WITH COMPARABLE CONTRIBUTIONS OCURRING AT Z=56. THIS EXPLABATUIB ASSUMES THAT ONLY TWO MECHANISMES ARE OPERATIVE AND THIS IS FAR FROM CERTAIN. THE RESULTS PRESENTED HERE PERMIT A DETERMINATION OF HOW THE ANGULAR DISTRIBUTION AND THE WIDTH OF THE SPECTRUM, QUANTITIES THAT CANNOT BE INFERRED FROM THICK-TARGET RECOIL STUDIES, CHANGE AS THE TRANSITION BETWEEN MECHANISMS IS ACCHIEVED./; ATH=(N.T.PORILE'1',S.PANDIAN'1',H.KLONK'1',C.R.RUDY'1',E.P.STEINBERG'2' INST-ATH=(1USAPUR'1',1USAANL'2'); REF=PR/C; VLP=19(1979)1832; RCTS=(238U(P,X)128BA,238U(P,X)131LA,238U(P,X)131BA,238U(P,X)135BA, 238U(P,X)140BA); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,6; RCT=(238U(P,X)128BA,238U(P,X)131LA,238U(P,X)131BA,238U(P,X)135BA, 238U(P,X)140BA); CHM=UF4; THK-TGT=100[300MU-M; BAC=AL; THK-BAC=20MU-M; ACC=(SYN); INST-ACC=1USAANL; INC-ENGY-RANGE=(11.5GEV'55'); /*@55@*/ DELTA-INC-ENGY=XKEV; ERS-PRJ=XKEV; BEAM-INTNSTY=XUA; POL-PRJ=NO; DET-PARTCL=(GAMMA); DET-SYS=(GE(LI)); /*@56@*/ /*@57@*/ BAC=X'54'; DET-PARTCL=(X); PHQ=(Z-DSTRN,X'60'); /*@60@*/ /*@61@*/ /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,6; INC-ENGY-LAB=11.5GEV; RSD=131LA'4'; THTL=90DEG; /*@4@*/ /*FIG.3-(F)*/ /* D327 FIG.3-(F) */ /* SER#= 4 */ /* XSCALE=LINEAR YSCALE=LINEAR */ /* XMAX= 1.80000000E+02 YMAX= 2.39999950E-01 */ /* XMIN= 0.00000000E+00 YMIN= 0.00000000E+00 */ /* FOLLOWING DATA ARE TAKEN FROM GRAPH */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; DATA'1' DATA-REL'3' DELTA-DATA-REL'3' (UNIT'2') (NODIM) (NODIM) 29.552 1.128E-01 XXXXXXXXX 27.537 1.797E-01 1.180E-02 26.866 1.639E-01 7.868E-03 40.298 1.443E-01 9.180E-03 42.313 1.469E-01 1.049E-02 47.686 2.033E-01 1.180E-02 57.089 2.098E-01 9.180E-03 59.104 1.679E-01 1.180E-02 65.149 2.413E-01 1.180E-02 75.224 2.308E-01 1.049E-02 70.522 1.443E-01 1.180E-02 80.597 1.862E-01 2.098E-02 87.985 1.443E-01 1.311E-02 91.343 1.010E-01 1.049E-02 101.418 1.220E-01 9.180E-03 106.119 9.180E-02 1.180E-02 113.507 1.141E-01 1.180E-02 120.895 8.262E-02 9.180E-03 125.597 4.066E-02 XXXXXXXXX 131.642 4.852E-02 XXXXXXXXX 142.388 2.754E-02 XXXXXXXXX 147.089 2.623E-02 XXXXXXXXX 152.463 7.869E-03 XXXXXXXXX 165.224 3.934E-03 XXXXXXXXX \END; /*===================================================================*/ |
