SUBENT 21965003 20060612 BIB 14 51 REACTION (28-NI-58(N,2N)28-NI-57,,SIG) FACILITY (CCW,2AUSIRK) IRK accelerator for the energy range 13.4 to 14.8 MeV, energy steps 0.04 to 0.15 MeV. METHOD (STTA) Stack target irradiation DETECTOR (SCIN) Li-I(Eu) scintillation detector for the time distribution of the neutron production DECAY-DATA (28-NI-57,,DG) MONITOR (13-AL-27(N,A)11-NA-24,,SIG) MONIT-REF (,S.TAGESEN+,R,FIZ-KA-13-1,1981) Cross section data taken from evaluation by Tagesen and Vonach, physics data 13-1,1981, Fachinformationszentrum Karlsruhe. DECAY-MON (11-NA-24,14.98HR,DG) COMMENT .The datum at e = 14.690 MeV resulted from a measurement at the van de graaff accelerator/cbnm. SAMPLE .Natural Ni, purity > 99.98 per cent .Each sample was packed together either with two or at least one aluminium foil for monitoring. STATUS .Data taken from 82ANTWERP paper and main ref. ERR-ANALYS .The principal sources of uncertainty were (ERR-S) Counting statistics as function of energy (ERR-2) Error due to masses for sampl eand reference including purity (ERR-3) Error due to the detector efficiency for sample radiation (ERR-4) Error due to the detector efficiency for Na-24 radiation (ERR-5) Max error due to the half-life of interfering Co-57 (ERR-6) Error due to the half-life of interfering Co-58-g (ERR-7) Max error due to half-life of Na-24 (ERR-8) Error due to flux gradient in sample (experimentally determined) (ERR-9) Max Error due to correction for elastic neutr scattering by samples and sample holder (ERR-10) Max Error arised from correction for neutron scattering effects due to target backind (ERR-11) Error due to room return background (ERR-12) Error due to correction for relatingthe measured cross section to the average neutron energy (MONIT-ERR) 27-Al(N,A)Na-24 reference cross section error FLAG (1.)
