154ND    248CM,252CF SF DECAY          94SM07,95ZH39            
         95ZH39 STUDIED THE DEEXCITATION OF HIGHLY EXCITED DOUBLY EVEN ^Ba,     
          ^Ce AND ^Nd NUCLIDES (ONE OF WHICH WAS 154ND) PRODUCED AS PRODUCTS    
          OF THE SPONTANEOUS FISSION OF 252CF. DOUBLE AND TRIPLE G              
          COINCIDENCES WERE MEASURED USING AN ARRAY OF 20 ^Compton-SUPPRESSED   
          ^Ge DETECTORS AT THE ^HHIRF AND THE EARLY IMPLEMENTATION OF           
          ^Gammasphere HAVING 36 LARGE ^Ge DETECTORS AND ONE ^LEPS DETECTOR.    
          XG AND XX COINCIDENCES WERE MEASURED USING TWO X-RAY DETECTORS        
          HAVING ENERGY RESOLUTIONS OF 280 ^eV AT 14 ^keV AND THREE ^Ge         
          DETECTORS. EG VALUES (WITHOUT UNCERTAINTIES), BUT NO RI DATA, WERE    
          GIVEN. LEVELS INTERPRETED AS MEMBERS OF THE GS (YRAST) BAND UP TO     
          THE 16+ STATE WERE REPORTED.                                          
         94SM07 STUDIED THE G RAYS EMITTED FROM HIGHLY EXCITED STATES OF THE    
          NEUTRON-RICH NUCLIDES 152ND, 154ND AND 156ND, PRODUCED IN THE         
          SPONTANEOUS FISSION OF 248CM. THE 248CM SOURCE CONSISTED OF AP 5 MG   
          OF ^curium ^oxide UNIFORMLY EMBEDDED IN A ^KCl PELLET. THE ^Eurogam   
          ^phase 1 ARRAY OF ^Compton-suppressed ^Ge DETECTORS WAS USED TO       
          DETECT THE G RADIATION. FROM ANALYSIS OF G-RAY COINCIDENCE DATA, THE  
          YRAST LEVEL STRUCTURE UP THROUGH THE 16+ STATE WAS DETERMINED. THESE  
          AUTHORS REPORT LEVEL ENERGIES (WITHOUT UNCERTAINTIES), FROM WHICH     
          EG VALUES MAY BE DEDUCED, BUT NO RI VALUES. USING A MODIFIED DSAM     
          TECHNIQUE (THE ^Doppler PROFILE METHOD), THEY MEASURED THE LIFETIMES  
          OF THE LEVELS INTERPRETED AS THE 12+, 14+ AND 16+ YRAST STATES.       
         EARLIER STUDIES OF THE G RAYS FROM THE SPONTANEOUS FISSION OF 252CF    
          HAVE BEEN CARRIED OUT BY 71CH44 (SEE ALSO 70CHYJ,70CHZH,70CHZM, AND   
          70WI16 FROM THESE SAME AUTHORS), 74JAYY (AND ALSO 74JAZN), AND
