C255800100010 SAMPLE The isotopically pure 249Cf was deposited on the Be C255800100011 backing foil as Cf203 in a 6 mm diam spot by the C255800100012 molecular deposition method, and the amount of Cf was C255800100013 measured by counting the 249Cf alpha particles in a C255800100014 low solid angle counting apparatus. C255800100015 DETECTOR (GELI,SIBAR) Five Ge(Li) or high purity Ge gamma ray C255800100016 detectors. Four 100 mm2 Si(Au) surface barrier C255800100017 detectors. C255800100018 METHOD (CHSEP,GSPEC,ASPEC) Chemical fractions of the C255800100019 individual actinide elements were prepared and the C255800100020 gamma, alpha, and spontaneous fission activities of C255800100021 the actinide isotopes were measured. C255800100022 ERR-ANALYS (DATA-ERR) The uncertainties quoted represent 1 sigma C255800100023 deviations and are meant to encompass uncertainties C255800100024 due to counting statistics and uncertainties in the C255800100025 detector efficiencies, the decay radiation abundances, C255800100026 the chemical yield, and in the beam intensity during C255800100027 irradiation. C255800100028 CORRECTION None of the cross sections in this table have been C255800100029 corrected for feeding from the decay of other C255800100030 nuclides during the bombardment. One exception to C255800100031 this is in the neutron-deficient Cm isotopes which C255800100032 are fed by the alpha decay of Cf isotopes. The C255800100033 feeding corrections in this case were so large that C255800100034 the neutron-deficient Cm cross sections are not C255800100035 presented in this work.
