The authors 2180600100041 point out that the two measurements were essentially 2180600100042 independent. 2180600100043 .Calculation of the exact 'effective' Pu sample masses.2180600100044 MONITOR (92-U-235(N,F),,SIG) 2180600100045 .Above 25 keV the ENDF/B-V data were assumed for 2180600100046 the fission cross section. 2180600100047 .Below 25 keV the assumed data are based on fission 2180600100048 cross section integrals as measured by Wagemans and 2180600100049 Deruytter (J,ANE,3,437,76). 2180600100050 ERR-ANALYS (ERR-1) additional normalization uncertainty is 5%, 2180600100051 mainly due to the effective mass calculation. 2180600100052 (ERR-2) .The number of Pu-244 atoms in the sample was 2180600100053 calculated with an 3% accuracy. 2180600100054 (ERR-3) .That of U-235 atoms with an 1% accuracy. 2180600100055 ADD-RES .The average cross sections in the MeV energy range 2180600100056 is found to be 12% larger than was deduced from 2180600100057 earlier measurements. 2180600100058 .The experimental results are discussed in view of 2180600100059 the fission barrier parameters of Pu-245. 2180600100060 HISTORY (19821108C) BN. 2180600100061 (19830111E) 2180600100062 (19830314A) a.P.T.
