C256000100008 cyclotron. C256000100009 SAMPLE Targets were prepared by vacuum volatilization of C256000100010 natural silicon onto thin nickel foils. The thickness C256000100011 of the silicon was approximately 170 microg/cm2. C256000100012 DETECTOR (SIBAR) 56-microm-thick transmission-mounted surface- C256000100013 barrier detector. C256000100014 ERR-ANALYS (ERR-S) The errors include only statistical C256000100015 uncertainties in the total number of events recorded. C256000100016 (ERR-SYS,,40.) The systematic error, due mainly to C256000100017 the incomplete detection discussed above and to the C256000100018 uncertainty in the target thickness, is believed to C256000100019 Be less than 40%.
