The source was 1432000100011 mounted on a piece of aluminum 0.010 inch thick and no 1432000100012 heavy shield material was used. 1432000100013 DETECTOR (NAICR,FISCH) 1/1.5 inch NaI(Tl) crystal, double- 1432000100014 crystal Compton spectrometer and gas scintillator 1432000100015 fast-fission detector. 1432000100016 METHOD (COINC,GSPEC,PHD) Pulse-height distribution from NaI 1432000100017 crystals were measured in coincidence with the pulses 1432000100018 from the fission detector. 1432000100019 CORRECTION The experimental parameters were adjusted to give a 1432000100020 compromise between energy resolution and sensitivity. 1432000100021 ERR-ANALYS (ERR-S ) Statistical accuracy of the measurement. No 1432000100022 details on error analysis. 1432000100023 HISTORY (20120202C) BP 1432000100024 ENDBIB 22 0 1432000100025 COMMON 1 3 1432000100026 ERR-S 1432000100027 PER-CENT 1432000100028 8. 1432000100029 ENDCOMMON 3 0 1432000100030 ENDSUBENT 29 0 1432000199999 SUBENT 14320002 20120202 13781432000200001 BIB 3 7 1432000200002 REACTION (98-CF-252(0,F)0-G-0,PR,FY/DE) Photon emission in 1432000200003 spontaneous fission. 1432000200004 STATUS (CURVE) Fig.3.
