C249800100011 SAMPLE An isotopically separated 178Hf target of thickness C249800100012 100 microg/cm2 was prepared in an isotope separator C249800100013 on a 60-microg/cm2 carbon foil. C249800100014 DETECTOR (SIBAR) Silicon surface-barrier semiconductor C249800100015 detectors, each of area 400 mm2 and a nominal C249800100016 depletion depth ~100 microm. C249800100017 METHOD (COINC) Double energy technique. C249800100018 Fission coincidence events were detected with C249800100019 three pairs of silicon surface-barrier semiconductor C249800100020 detectors placed inside the 162-cm-diam scattering C249800100021 chamber at IUCF. Detectors were calibrated with a C249800100022 252Cf source. Approximately 2100 valid coincidence C249800100023 events were observed during the course of these C249800100024 experiments. Of these, about 12% were attributed to C249800100025 actinide fission. Of the remaining 1850 events, it C249800100026 was estimated that less than 3% of these could be due C249800100027 to heavy-element fission.
