HERE, ONLY THREE DECAY CHANNELS ARE OPEN: 17O+P, 14N+ALPHA AND 18F+GAMMA AND THUS A KNOWLEDGE OF THREE OF THE REACTIONS INVOLVING THESE CHANNELS DEFINES UNIQUELY THE PARTIAL WIDTHS OF THE STATES. THIS PAPER REPORTS THE INVESTIGATION OF A THIRD OF THESE REACTIONS./; ATH=(W.E.KIESER'1',R.E.AZUMA'1',K.P.JACKSON'1'); INST-ATH=(1CANTOR'1'); REF=NP/A; VLP=331(1979)155; RCTS=(17O(P,ALPHA)14N); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,5; ENR=NAT; CHM=WO3'1'; /*@3@*/ THK-TGT=XMG/CM**2; BAC=TA; /*@4@*/ THK-BAC=XMG/CM**2; POL-TGT=NO; ALGN-TGT=NO; ENR=NAT; CHM=TI.O2'1'; /*@5@*/ THK-TGT=XMG/CM**2; BAC=X'1'; /*@4@*/ THK-BAC=XMG/CM**2; POL-TGT=NO; ALGN-TGT=NO; ACC=(VDG); INST-ACC=1CANTOR; INC-ENGY-LAB-RANGE=(0.4[0.95MEV); DELTA-INC-ENGY-LAB=0.2KEV; ERS-PRJ=XKEV; BEAM-INTNSTY=30UA; POL-PRJ=NO; ACC=(VDG); INST-ACC=1CANMCM; INC-ENGY-LAB-RANGE=(0.74[1.5MEV); DELTA-INC-ENGY-LAB=1.0KEV; ERS-PRJ=XKEV; BEAM-INTNSTY=30UA; POL-PRJ=NO; DET-PARTCL=(ALPHA); DET-SYS=(SBD); SOLID-ANGL=XMSR; ERS-DET=16[19KEV; ANL=(RMTRX-THEORY); PHQ=(XSECTN,EXC-FUNCT,DSIGMA/DOMEGA,RESN-ENGY,WDTH-RATIO,SPEC-AMPL); /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,5; INC-ENGY-LAB=0.4[1.4MEV; CMPD=18F; THTL=135DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; EXC-ENGY INC-ENGY-LAB J-PI WDTH DELTA-WDTH CHNL-PARTCL CHNL-SPIN CHNL-ANG-MMT DATA1'1' PART-WDTH DELTA-PART-WDTH DATA2'2' (KEV) (KEV) (NODIM) (EV) (EV) (NODIM) (NODIM) (NODIM) (NODIM) (EV) (EV) (NODIM) 6095 518 4- 244 31 P 3 1 + 135 26 0.031 6095 518 4- 244 31 P 3 3 + 3 0.6 0.973 6095 518 4- 244 31 ALPHA 1 3 + 106 17 0.206 6102 525 1?+? 34 3.3 P 2 2 + 0.2 0.02 0.0010 6102 525 1?+? 34 3.3 ALPHA 1 0 + 33.6 3.3 0.0013 6161 588 3+ 14000 500 P 3 0 + 14000 500 0.277 6161 588 3+ 14000 500 ALPHA 1 2 + 5.0 0.6 0.0010 6240 670.5 3- 193 25 P 2 1 + 34.5 5.8 0.0020 6240 670.5 3- 193 25 P 3 1 + 23.7 4.0 0.0014 6240 670.5 3- 193 25 ALPHA 1 3 - 133.0 23.8'3' 0.122 6242 673.0 3- 178 35 P 2 1 + 24.2 3.1 0.0014 6242 673.0 3- 178 35 P 3 1 + 16.6 2.1 0.0010 6242 673.0 3- 178 35 ALPHA 1 3 + 137.0 34.7'3' 0.123 6256 688 1+ 602 120 P 2 2 + 27 3 0.027 6256 688 1+ 602 120 ALPHA 1 0 + 575 120 0.011 6282 716 2+ 10000 500 P 2 0 - 10000 500 0.082 6282 716 2+ 10000 500 ALPHA 1 2 + 27 3 0.0032 6310 746 3+ 951 142 P 3 0 + 525 117 0.0036 6310 746 3+ 951 142 ALPHA 1 2 - 426 82 0.045 6384 824 2+ 395 88 P 2 0 + 8.6 1.3 0.00004 6384 824 2+ 395 88 P 2 2 - 44.6 6.9 0.017 6384 824 2+ 395 88 P 3 2 - 56.1 8.7 0.021 6384 824 2+ 395 88 ALPHA 1 2 + 286.0 87 0.022 6481 927 3+ 400 94 P 3 0 - 216 87 0.00066 6481 927 3+ 400 94 P 3 2 - 61 25 0.013 6481 927 3+ 400 94 ALPHA 1 2 + 123 25 0.0066 6564 1015 5+ 561 132 P 3 2 + 1.2 0.13 0.00016 6564 1015 5+ 561 132 ALPHA 1 4 + 560 132 1.06 6635 1090 1- 80000 2000 P 2 1 + 2720 312 0.020 6635 1090 1- 80000 2000 P 2 3 - 200 23 0.603 6635 1090 1- 80000 2000 ALPHA 1 1 + 77090 2000 0.795 6643 1098 2- 599 73 P 2 1 - 192 45 0.0014 6643 1098 2- 599 73 P 3 1 - 176 41 0.0012 6643 1098 2- 599 73 ALPHA 1 1 + 231 40 0.0023 6783 1247 4+ 9150 1000 P 2 2 + 6000 820 0.309 6783 1247 4+ 9150 1000 P 3 2 + 3000 580 0.155 6783 1247 4+ 9150 1000 ALPHA 1 4 + 150 24 0.119 6807 1272 2- 88070 2000 P 2 1 + 3430 395 0.014 6807 1272 2- 88070 2000 P 3 1 + 13140 1500 0.054 6807 1272 2- 88070 2000 ALPHA 1 1 + 71500 2000 0.470 6811 1276 2?+? 2960 455 P 2 0 + 2750 450 0.0032 6811 1276 2?+? 2960 455 ALPHA 1 2 + 210 67 0.0039 6869 1338 3?-? 5030 1000 P 2 1 + 5000 1000 0.017 6869 1338 3?-? 5030 1000 ALPHA 1 3 + 30 7 0.0023 \END; /*===================================================================*/ |
