GAMMA-RAY CASCADES HAVE BEEN STUDIED BY MEANS OF GAMMA-GAMMA COINCEDENCES. TWO ISOMERIC STATES HAVE BEEN IDETIFIED, NAMELY THE 200.6 KEV(4+) STATE WITH MEAM LIFE-TIME = 11.8+-0.1 MICRO-SEC AND THE 243.9 KEV(6+) STATE WITH MEAM LIFE-TIME = 4.7+-0.3 MICRO-SEC. AN UPPER LIMIT MEAN-HALF-LIFE < 4 NANO-SEC HAS BEEN ASSIGNED FOR THE MEAM LIFE OF SEVEN OTHER LEVELS./; ATH=(M.BIMI'1',A.M.BIZZETI-SOMA'1',P.BLASI'1',M.LORINI'1', N.TACCETTI'1'); INST-ATH=2ITYFIR'1'; REF=PR/C; VLP=21(1980)116; RCTS=(100MO(P,N,GAMMA)100TC); /*===================================================================*/ /* Experimental Conditions */ /*===================================================================*/ \\EXP,1; RCT=100MO(P,N,GAMMA)100TC; ENR=97.42%; CHM=X'1'; /*@21@*/ THK-TGT=[100UG/CM**2; BAC=(SELF,X'2'); /*@22@*/ ACC=(VDG); INST-ACC=2ITYPAD; INC-ENGY-RANGE=(4MEV,6.8MEV); DET-PARTCL=(GAMMA); DET-SYS=(GE'3',GE(LI)'4'); ERS-DET=([0.5KEV'3',[2.5KEV'4'); /*@23@*/ /*@24@*/ DET-PARTCL=(ELECTRON); DET-SYS=(MAG,SI(LI)); ERS-DET=[4KEV; ANL=(X'5'); /*@25@*/ PHQ=(EXC-ENGY,LIFE,SPIN,PTY,X'6'); /*@26@*/ /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,1; RSD=100TC; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; EXC-ENGY J-PI LIFE-AVER LIFE-AVER-ERR LIFE-AVER-UP (KEV) (NODIM) (USEC) (USEC) (USEC) 172.1 2+ X X 4 200.6 4+ 11.8 0.1 X 223.5 2- X X 4 243.9 6+ 4.7 0.3 X 263.6 3+ X X 4 287.5 5+ X X 4 299.5 X X X 4 335.2 X X X 4 355.6 X X X 4 \END; /*===================================================================*/ |
