(2D5/2)(-1), (!!)(1G9/2)(-1) , AND (!!!)(2P)(-1) AND (1G)(-1) IN THE RESIDUAL 91ZR NUCLEUS. THEY INDICATE THE MICROSCOPIC PARTICLE-HOLE CONFIGURATION OF THE GIANT QUADRUPOLE RESONANCE. THE DIRECT FAST DECAY BRANCH IS ABOUT 16%./; ATH=(H.OHSUMI'1',H.EJIRI'1',T.SHIBATA'1',Y.NGAI'1',K.OKADA'1', T.MOTOBAYASHI'1,2'); /*@3@*/ INST-ATH=(2JPNOSA'1'); REF=PR/C; VLP=32(1985)1789; RCTS=(92ZR(4HE,4HE,N)91ZR,92ZR(4HE,4HE,N)92ZR); PHQS=(ENGY-SPEC,DSIGMA/DOMEGA/DE,DSIGMA/DOMEGA/DOMEGA/DE,ANGL-CORRL); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,8; ACC=(CYC); INST-ACC=2JPNRCN; INC-ENGY-LAB=(109MEV); ANL=(PWBA,COLL-MODEL); PHQ=(ENGY-SPEC,DSIGMA/DOMEGA/DE,DSIGMA/DOMEGA/DOMEGA/DE,ANGL-CORRL); RCT=92ZR(4HE,4HE,N)91ZR; DET-PARTCL=(N'3',ALPHA'4'); COINC=(ALPHA,N); ANT-COINC=NO; DET-SYS=(SSD'4',SCT'3',CNTR-TLSCP'4',TOF'3'); /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,8; INC-ENGY-LAB=109MEV; THTL=14.9[16.9DEG'5',110DEG'6'; /*@4@*/ /*@6@*/ /*@7@*/ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; ENGY-EMT-LAB'10' DSIGMA/DOMEGA/DOMEGA/DE DELTA-DSIGMA/DOMEGA/DE/DOMEGA/DE (MEV) (ARB) (ARB) /*FIG.3-(3)*/ \END; /*===================================================================*/ |
