reactor with position precision of less than 1 cm 2307500100015 SAMPLE 70 micro-liter HCL solution of 237Np (~3 kBq) in a 2307500100016 quartz tube with a wall thickness of 1 mm (~ 30 mm 2307500100017 in length and 6 mm in outer diameter). 2307500100018 Number of 238Np nuclei was determined by gamma-rays 2307500100019 emitted from 233Pa, which was equilibrated with 237Np.2307500100020 The 237Np was wrapped in Al foil together with Au foil 2307500100021 (99.95% purity, 0.1 mm thick, 5.6395+/-0.0001 mg). 2307500100022 DETECTOR (HPGE) 90% efficiency relative to 7.6 cm long and 2307500100023 7.6 cm diameter NaI(Tl) detector and 2.4 keV FWHM at 2307500100024 1333 keV gamma-peak of 60Co. 2307500100025 Sample was set at 150.0+/-0.5 mm distance from the end 2307500100026 window of Ge detector. 2307500100027 Sample and detector were shielded by lead blocks of 2307500100028 5-10 cm thickness. 2307500100029 Full-energy peak efficiency of Ge detector was 2307500100030 calibrated using standard gamma-ray sources: 2307500100031 133Ba, 152Eu and 60Co source 2307500100032 METHOD (ACTIV) Irradiated for 3.3167 hr at 2000+/-10 W 2307500100033 (GSPEC) 238Np and 233Pa activities were measured twice:2307500100034 Started at 18.1767 hr,ended at 20.6783 hr (2.4867 hr);2307500100035 Started at 24.1083 hr,ended at 40.7753 hr(16.5881 hr).2307500100036 Also 198Au activities were measured: 2307500100037 Started at 22.5300 hr,ended at 22.6967 hr(0.16361 hr) 2307500100038 Parenthesized time shows the live time of measurement. 2307500100039 ANALYSIS Spectrum averaged cross section was derived with an 2307500100040 evaluated data library in the following procedure: 2307500100041 1.C/E of reaction rate was obtained for the library. 2307500100042 2.Representative neutron energy corresponding to 50% 2307500100043 of the reaction rate was calculated for the library.2307500100044 3.Cross section at the representative neutron energy 2307500100045 of the library was divided by the C/E to obtain 2307500100046 the experimental cross section. 2307500100047 DECAY-DATA (93-NP-238,2.117D,DG,984.,0.252) 2307500100048 T1/2=2.117+/-0.002 days, I(gamma)=25.2+/-0.5% 2307500100049
