The isotopic composition 2189500100016 was 0.68% Pu-239, 98.47% Pu-240, 2189500100017 0.48% Pu-241 and 0.37% Pu-242. 2189500100018 The Pu-239 sample consisted of a 118 micro-g/cm-sq 2189500100019 PuF3 layer on the same backing as Pu-240. The 2189500100020 isotopic abundance of Pu-239 was 99.98%. 2189500100021 The diameter of the active layer was 25 mm in both 2189500100022 cases 2189500100023 METHOD .Each spontaneous fission experiment was accompanied 2189500100024 by a calibration Pu-240(g,f) run with 20-MeV 2189500100025 bremsstrahlung. The Pu-240 photofission runs were 2189500100026 calibrated by Pu-239(n,f) with thermal neutrons 2189500100027 using a calibration procedure according to (PR, 2189500100028 137,B837,1965) and parameters from (PR,149,894,1966). 2189500100029 These Pu-239(n,f) measurements were done with a 2189500100030 well-thermalized and collimated neutron beam 2189500100031 from the reactor. 2189500100032 REL-REF (M,13081001,H.W.Schmitt+,J,PR,137,B837,1965) 2189500100033 (R,,J.N.Neiler+,J,PR,149,894,1966) 2189500100034 DETECTOR (SOLST)2 Ortec F-series heavy ion detectors (CF090-600 2189500100035 -60) mounted symmetrically on both sides of the 2189500100036 fission sample at a distance of 7 cm from the sample 2189500100037 and at the angle of 90 degrees to the bremsstrahlung 2189500100038 or neutron beam axis. 2189500100039 ANALYSIS .Off line, the data were sorted in two-dimensional 2189500100040 provisional mass (My) and total kinetic (Ek) arrays, 2189500100041 120 * 120 channels. 2189500100042 COMMENT .The reference also contains data on Pu-240(g,f) 2189500100043 using gammas from bremsstrahlung. 2189500100044 CORRECTION .For 2189500100045 - spontaneous fission of other Pu-isotopes 2189500100046 - drift in the measuring system 2189500100047 STATUS (COREL,L0105001) Pu-240(g,f) using gammas from 2189500100048 bremsstrahlung. 2189500100049 ERR-ANALYS (ERR-1) Uncertainty in target thickness was about 2% 2189500100050 HISTORY (19831118C) A.L. 2189500100051 (19840202E) 2189500100052 (20090401A) Date is corrected.
