A056800100004 AUTHOR (N.G.Zaitseva,E.Rurarz,M.B.Tchikalov,M.Vobecky, A056800100005 V.A.Khalkin,L.M.Popinenkova) A056800100006 INSTITUTE (4ZZZDUB,3POLIPJ,3CZRCZA,4RUSFVE) A056800100007 REFERENCE (J,RCA,65,157,1994) A056800100008 FACILITY (LINAC,4RUSFVE) Lu-100 at the Institute For High EnergyA056800100009 Physics in Serpukhuv (RUSSIA). A056800100010 SAMPLE High purity natural V in metallic form was used as a A056800100011 target material for irradiations. The thicknesses of V A056800100012 foils were determined by weight and area measurements A056800100013 for each individual foil. The stack consisting of 25 A056800100014 numbered circular V foils (the foils weighed between- A056800100015 0.8573 g and 0.8950 g ,had thicknesses about 0.5 mm A056800100016 and were cut into 19 mm diam. discs) was exposed to A056800100017 an external proton beam. A056800100018 MONITOR (13-AL-27(P,X)11-NA-22,CUM,SIG,,,EVAL) - adopted valuesA056800100019 MONIT-REF (,J.Tobailem+,R,CEA-N-1466,1971) A056800100020 DETECTOR (HPGE) The gamma-ray spectra from separate foils were A056800100021 measured using a computerized gamma-spectroscopy A056800100022 system, CICERO-8K equipped with a HPGe detector in JINRA056800100023 The spectrometer was calibrated for gamma-ray energy A056800100024 using calibrated radionuclide sources of 133Ba A056800100025 and 152Eu. A056800100026 METHOD (STTA,ACTIV,BCINT,EXTB) A056800100027 (GSPEC) A056800100028 A target containing 7.7 g/cm**2 25 foils in the stack A056800100029 of vanadium was bombarded at a proton beam current of A056800100030 160 nanoAmperes approximately for 406 hours -during A056800100031 intermittent bombardment over a period of 4.5 years. A056800100032 ERR-ANALYS (DATA-ERR) The total errors in the cross section were A056800100033 obtained by taking square roots of the sums of the A056800100034 squares of all the individual errors, like those in: A056800100035 * the detection efficiency, A056800100036 * counting geometry and statistics, A056800100037 * attenuation corrections, A056800100038 * irradiation and cooling times, A056800100039 * proton beam monitoring, A056800100040 * decay schemes, A056800100041 * computer spectral integration, etc. A056800100042 The resulting total error is thus partly systematic A056800100043 and amounts to between 15-20%. Authors assumed for the A056800100044 cross sections an error of 20%.
