To avoid 3031700100018 delta-E detector from overloading by FF and the natural3031700100019 alpha radioactivity of the target, a 13 mg/cm2 tantalum3031700100020 window was used. 3031700100021 As E-detector, a surface-barrier silicon detector with3031700100022 a depletion layer of 300 micron was placed inside pro- 3031700100023 portional counter. 3031700100024 PART-DET (FF) He,Li, or Be as ternary particle of fission. 3031700100025 HISTORY (19760106C) KO. 3031700100026 (20090115A) SD: BIB section updated 3031700100027 ENDBIB 25 0 3031700100028 COMMON 1 3 3031700100029 EN-DUMMY 3031700100030 EV 3031700100031 2.5300E-02 3031700100032 ENDCOMMON 3 0 3031700100033 ENDSUBENT 32 0 3031700199999 SUBENT 30317003 20090115 31343031700300001 BIB 5 16 3031700300002 REACTION ((92-U-235(N,F)ELEM,TER/CHG,FY)/ 3031700300003 (92-U-235(N,F)2-HE-4,TER,FY)) 3031700300004 ANALYSIS The Li- and Be-intensities relative to the emission of 3031700300005 100 alpha particles were calculated with 3031700300006 the extrapolated spectrum of alpha particles, 3031700300007 the measured parts of the Li and Be spectra 3031700300008 (''experimental yields''), and 3031700300009 the extrapolated spectra of these nuclei 3031700300010 (''extrapolated yields''). 3031700300011 The extrapolation was performed assuming a symmetrical 3031700300012 shape of the energy distributions of all particles. 3031700300013 MISC-COL (MISC1) threshold (MeV) 3031700300014 (MISC2)'experimental yield' 3031700300015 STATUS (TABLE) Data from table 1 of Nucl.Phys.,A127(1969)495. 3031700300016 ERR-ANALYS (DATA-ERR) No further information. 3031700300017 (MISC2-ERR)'experimental yield error' 3031700300018 ENDBIB 16 0 3031700300019 NOCOMMON 0 0 3031700300020 DATA 6 2 3031700300021 ELEMENT DATA DATA-ERR MISC1 MISC2 MISC2-ERR 3031700300022 NO-DIM NO-DIM NO-DIM MEV PC/FIS PC/FIS 3031700300023 3.0000E+00 1.2000E-03 2.0000E-04 1.1500E+01 8.8000E-02 2.0000E-033031700300024 4.0000E+00 3.7000E-03 4.0000E-04 1.7100E+01 1.8500E-01 2.0000E-033031700300025 ENDDATA 4 0 3031700300026 ENDSUBENT 25 0 3031700399999 ENDENTRY 2 0 3031799999999
