WE DEMONSTRATE THAT THIS TYPE EXPERIMENT IS SENSITIVE TO THE IMAGINARY PART OF THE DOMINANT(MONOPOLE) ATOMIC IONIZATION AMPLITUDES. THE PRESENT EXPERIMENTAL RESULTS SUGGEST THAT THIS IMAGINARY PART MAY NOT BE WELL UNDERSTOOD./; ATH=(J.S.BLAIR'1',P.DYER'1',K.A.SNOVER'1',T.A.TRAINOR'1'); INST-ATH=(1USAWAU'1'); REF=PRL; VLP=41(1978)1712; RCTS=(58NI(P,P)58NI); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,1; RCT=58NI(P,P)58NI; ENR=X%; CHM=ELM; THK-TGT=9UG/CM**2; BAC=C; THK-BAC=2.0UG/CM**2; POL-TGT=NO; ALGN-TGT=NO; ACC=(X); INST-ACC=X; INC-ENGY-LAB-RANGE=(3.12[3.18MEV); DELTA-INC-ENGY-LAB=XKEV; ERS-PRJ=<1KEV; BEAM-INTNSTY=[0.8NA; POL-PRJ=NO; DET-PARTCL=(X-RAY,P); DET-SYS=(SI,NAI,SSD); SOLID-ANGL=XMSR; ERS-DET=60KEV; ANL=(X'1'); /*@3@*/ PHQ=(XSECTN,EXC-FUNCT); /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,1; INC-ENGY-LAB-RANGE=3.12[3.18MEV; /*FIG.1-(A)*/ /* D299 FIG.1-(A) */ /* SER#= 2 */ /* XSCALE=LINEAR YSCALE=LINEAR */ /* XMAX= 3.18000000E+03 YMAX= 5.00000000E+00 */ /* XMIN= 3.13000000E+03 YMIN= 2.00000000E+00 */ /* FOLLOWING DATA ARE TAKEN FROM GRAPH */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; INC-ENGY-LAB DATA1'1' (KEV) (ARB) 3124.57 4.51E+00 3134.82 4.41E+00 3138.81 4.43E+00 3140.96 4.47E+00 3142.81 4.24E+00 3144.65 4.30E+00 3146.60 4.07E+00 3148.75 3.06E+00 3149.77 2.63E+00 3150.59 2.36E+00 3151.62 2.58E+00 3152.44 2.99E+00 3154.69 3.59E+00 3156.74 4.02E+00 3160.74 4.39E+00 3164.84 4.26E+00 3174.88 4.44E+00 \END; /*===================================================================*/ |
