Sci. Eng. (to be published)" 3096500100006 AUTHOR (S.Amiel,T.Izak-Biran) 3096500100007 TITLE Odd-even systematics in neutron fission yields of 233U 3096500100008 and 235U 3096500100009 INC-SPECT Phys.Rev.C 11(1975)845: for bulk of data in Table IV: 3096500100010 fission spectrum with average energy of 1.9 MeV. 3096500100011 METHOD no information as original source of data is unknown 3096500100012 COMMENT Compiler's (ML) comment: the origin of the yield value 3096500100013 compiled by B.F.Rider and included here is not clear: 3096500100014 - The Rider file contains the value given in the data 3096500100015 table (Subentry 2) associated with the reference 3096500100016 74AMI2. 3096500100017 - The Rider reference files gives under 74AMI2: 'Amiel,3096500100018 S., Izak-Biran,T., To be published (1974). Cited in 3096500100019 74AMI1.' 3096500100020 - For 74AMI1 the Rider reference file states: 'Amiel, 3096500100021 S., Feldstein, H., "Odd-Even Systematics in Neutron 3096500100022 Fission Yields of Uranium Isotopes 233 and 235", 3096500100023 submitted to Phys.Rev.C (July 1974). See 75AMI1'. 3096500100024 - For 75AMI1 the Rider reference file gives Phys.Rev.C 3096500100025 11(1975)845 (which is taken as the main reference for3096500100026 this entry). 3096500100027 Compiler (ML) assumes that 74AMI1 and 75AMI1 are the 3096500100028 same reference. 3096500100029 - Table IV of Phys.Rev.C 11(1975)845 contains the same 3096500100030 value as the Rider file; therefore it is used as the 3096500100031 main reference for this entry. 3096500100032 - This table contains a footnote b) to the fractional 3096500100033 yield value giving 'Reference 31' as its origin. 3096500100034 Reference 31 is given as: 'S.Amiel and T.Izak-Biran, 3096500100035 Nucl.Sci.Eng. (to be published)'. 3096500100036 The compiler (ML) identified this reference as: 3096500100037 T.Izak-Biran and S.Amiel, "Reevaluation of the Emission3096500100038 Probabilities of Delayed Neutrons from Fission 3096500100039 Products", Nucl.Sci.Eng. 57(1975)117. (There is no 3096500100040 other paper by these authors in Nucl.Sci.Eng. during 3096500100041 the years 1974-1976). However: 3096500100042 - this reference presents an evaluation of delayed 3096500100043 neutron yields. All data presented are evaluated or 3096500100044 taken from another source. 3096500100045 - It contains for fast fission only delayed neutron 3096500100046 group yields (Table III) but no yields for individual3096500100047 precursors and hence none for Br-87. 3096500100048 - Even if one assumes that the group 1 consists only of3096500100049 Br-87, the delayed neutron yield (for 10% odd-even 3096500100050 effect) of 4.8, divided by the given Pn-value of 2.353096500100051 for Br-87, gives a cumulative yield of 2.04, which, 3096500100052 divided by the chain yield of 2.55 (given in Table IV3096500100053 of Phys.Rev.C 11(1975)845 along with the fractional 3096500100054 cumulative yield of 0.87), gives a fractional 3096500100055 cumulative yield of 0.80. 3096500100056 Conclusions: 3096500100057 - Nucl.Sci.Eng. 57(1975)117 is not the source of the 3096500100058 compiled value. 3096500100059 - It is even not known whether the value is the result 3096500100060 of an experiment and whether it originates from this 3096500100061 laboratory. 3096500100062 Therefore it is recommended not to use that value in an3096500100063 evaluation without any further information on, or 3096500100064 confirmation of, its origin and nature. 3096500100065 STATUS (RIDER) reference 74AMI2, checked by ML: see comment 3096500100066 HISTORY (19881017T) NNDC: converted from RIDER to EXFOR90588 3096500100067 (19911125A) ML: converted to regular EXFOR; comment and3096500100068 BIB informatio added, EN-MEAN changed. 3096500100069 (20010705A) ML: checked all sources again and revised 3096500100070 BIB section, in particular 'REFERENCE' and the 3096500100071 comment.
