C253200100010 INC-SPECT On average 3x10**12 ions/sec. C253200100011 SAMPLE The target was prepared by subliming 259 microg of C253200100012 249Cf as CfF3, onto a 27-microg/mm2 substrate of C253200100013 99.999% pure Al. C253200100014 DETECTOR (SIBAR) 50-mm2 and 100-mm2 Si(Au) surface barrier C253200100015 detectors. C253200100016 PART-DET (A) C253200100017 METHOD (ASPEC,ACTIV) Authors infer from these data that the C253200100018 new activity decays by emission of 9.06- and 9.25-MeV C253200100019 alpha particles to 259Rf and, therefore, can belong C253200100020 only to 263Sg. Some 22 atoms of recoil-transferred C253200100021 259Rf were observed to decay in the off-wheel C253200100022 detectors. Shortly after these daughter events, C253200100023 granddaughter 255No alpha particles were detected C253200100024 from four off wheel daughter decays. C253200100025 ANALYSIS From the rate of producing our 263Sg activity, authors C253200100026 calculate a formation cross section. C253200100027 DECAY-DATA (106-SG-263,0.9SEC,A) Measured by authors.
