A FIT WAS OBTAINED WITH A STANDARD DEVIATION OF 13KEV FOR 33 EXPERIMENTAL ENERGIES. THERE ARE, HOWEVER, SEVERAL REPORTED DISPLACEMENT ENERGIES WHICH DIFFER BY MORE THAN 35KEV FROM CALCULATION, NAMELY FOR THE PAIRS 46SC(0+,3)-46CA (0+,3), 46TI(4+,2)-46SC(4+,2) AND 52FE(6+,1)-52MN(6+,1) DEVIATIONS OF THIS MAGNITUDE,IF CORRECT, MIGHT ARISE FROM EXCEPTIONALLY LARGE CONFIGURATION ADMIXTURES, ISOSPIN MIXING OR OTHER INTERESTING STRUCTUAL ANOMALIES. WE HAVE,THEREFORE, CARRIED OUT NEW MEASUREMENTS FOR THESE THREE PAIRS./; ATH=(R.T.KOUZES'1',P.KUTT'1',D.MUELLER'1',R.SHERR'1'); INST-ATH=(1USAPTN'1'); REF=NP/A; VLP=309(1978)329; RCTS=(45TI(P,T)43TI, 46TI(P,T)44TI, 48TI(P,T)46TI, 50TI(P,T)48TI, 46TI(P,D)45TI, 50TI(P,D)49TI, 46TI(P,3HE)44SC, 48TI(P,3HE)46SC, 50TI(P,3HE)48SC,52CR(P,T)50CR, 52CR(P,3HE)50V, 54FE(P,T)52FE, 54FE(P,3HE)52MN); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,20; RCT=52CR(P,T)50CR; ENR=99.9%; /*@13@*/ CHM=ELM; THK-TGT=54UG/CM**2; BAC=SELF; POL-TGT=NO; ALGN-TGT=NO; ACC=(CYC); INST-ACC=1USAPTN; INC-ENGY-LAB-RANGE=(42[46MEV); DELTA-INC-ENGY-LAB=0.6KEV'1'; /*@14@*/ ERS-PRJ=XKEV; BEAM-INTNSTY=XUA; POL-PRJ=NO; DET-PARTCL=(T); DET-SYS=(PLST-SCT+X'1'); /*@4@*/ SOLID-ANGL=14MSR; ERS-DET=6KEV; ANL=(SHELL-MODEL); PHQ=(XSECTN,ENGY-SPEC,XSECTN-RATIO,RESN-ENGY,IAS,COULOMB-DISP-ENGY); /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,20; INC-ENGY-LAB=42.13MEV; RSD=50CR; J-PI=0+; ISOSPIN=3; THTL=21DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; QVL DELTA-QVL EXC-ENGY DELTA-EXC-ENGY (KEV) (KEV) (KEV) (KEV) -26041 6 13222 6 \END; /*===================================================================*/ |
