156ND    248CM,252CF SF DECAY          94SM07,95ZH39            
         94SM07: 156ND PRODUCED IN THE SPONTANEOUS-FISSION DECAY OF 248CM. THE  
          SOURCE CONSISTED OF AP 5 MG OF ^curium oxide MIXED WITH 65 MG ^KCl    
          AND PRESSED IN THE FORM OF A 7-^mm DIAMETER PELLET. THE EMITTED G     
          RADIATION WAS STUDIED USING THE ^EUROGAM PHASE 1 ARRAY OF             
          ^Compton-suppressed ^Ge DETECTORS. MEASURED THE LIFETIMES OF THE      
          LEVELS INTERPRETED AS THE 12+, 14+ AND 16+ MEMBERS OF THE YRAST       
          (i.e., GS) BAND USING A MODIFIED DSAM TECHNIQUE (THE ^Doppler         
          PROFILE METHOD). ALSO MEASURED EG, BUT REPORT ONLY LEVEL ENERGIES     
          WITH NO UNCERTAINTIES.                                                
         95ZH39: 156ND OBTAINED AS A PRODUCT OF THE SF DECAY OF 252CF. THE      
          252CF SOURCE STRENGTH WAS AP 6|*10{+4} FISSIONS/S. THE G RADIATION    
          WAS STUDIED USING AN ARRAY OF 20 ^Compton-suppressed ^Ge DETECTORS,   
          WITH EG, GG, BEING MEASURED. G RADIATION, INCLUDING GGG, WAS ALSO     
          MEASURED USING THE EARLY IMPLEMENTATION OF ^Gammasphere, HAVING 36    
          LARGE ^Ge DETECTORS AND ONE LOW-ENERGY PHOTON SPECTROMETER. XX AND XG 
          COINCIDENCES WERE MEASURED USING TWO ^x-ray DETECTORS HAVING          
          RESOLUTIONS OF 280 EV AT 14 KEV AND THREE ^Ge DETECTORS. AUTHORS      
          REPORT EG VALUES ONLY, WITH  NO UNCERTAINTIES.                        
         BOTH STUDIES SHOW THE GS BAND UP THROUGH THE 16+ BAND MEMBER AND NO    
          OTHER EXCITED STATES. THESE TWO SCHEMES ARE IN ESSENTIAL AGREEMENT.
