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,13; 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'53'; /*@53@*/ DET-PARTCL=(X); SOLID-ANGL=0.16SR'63'; /*@63@*/ PHQ=(ANGL-DSTRN'64,65,66,67'); /*@58@*/ /*@59@*/ /*@64@*/ /*@65@*/ /*@67@*/ /*@66@*/ ANL=(X'68'); /*@68@*/ /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,13; RSD=131LA'4'; /*@4@*/ /*FIG.4-(F)*/ /* D327 FIG.4-(F) */ /* SER#= 8 */ /* XSCALE=LINEAR YSCALE=LINEAR */ /* XMAX= 1.80000000E+02 YMAX= 1.29999924E+00 */ /* XMIN= 0.00000000E+00 YMIN= 6.99999988E-01 */ /* FOLLOWING DATA ARE TAKEN FROM GRAPH */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; THTL DATA-REL'3,10' DELTA-DATA-REL (DEG) (NODIM) (NODIM) 22.765 1.242E+00 8.421E-02 36.529 8.737E-01 6.842E-02 50.823 1.116E+00 3.157E-02 66.176 1.005E+00 3.157E-02 82.588 1.116E+00 3.684E-02 96.353 1.032E+00 5.263E-02 114.882 1.005E+00 3.157E-02 128.647 8.368E-01 7.894E-02 143.470 9.474E-01 9.999E-02 157.235 9.000E-01 3.157E-02 \END; /*===================================================================*/ |
