C248800100008 (J,ZP/A,274,131,1975) Review of results. C248800100009 #doi:10.1007/BF01408465 C248800100010 INSTITUTE (1USAMRY) C248800100011 FACILITY (CYCLO,1USAMRY) The University of Maryland cyclotron. C248800100012 SAMPLE Isotopically enriched 238U and monoisotopic 209Bi and C248800100013 197Au targets were prepared by vacuum evaporation C248800100014 onto carbon films. Target material thicknesses were C248800100015 in most cases 80-140 microg/cm2 and backing C248800100016 thicknesses ranged from 20 to 100 microg/cm2. C248800100017 DETECTOR (SIBAR) A heavy ion surface-barrier semiconductor C248800100018 detector placed on one side of the beam axis and a C248800100019 50x6-mm position- sensitive semiconductor detector. C248800100020 The position-sensitive detector (PSD) was mounted 15 C248800100021 cm from the target and intercepted approximately +-10 C248800100022 degrees of the reaction plane. C248800100023 METHOD (MAGFR) The measurements reported here were performed C248800100024 in a 75-cm diam scattering chamber using a C248800100025 magnetically analyzed and focused beam of 140- and C248800100026 150-MeV 4He ions from the University of Maryland C248800100027 cyclotron. C248800100028 ERR-ANALYS (DATA-ERR) Experimental errors. C248800100029 CORRECTION Appropriate corrections for angular geometry were C248800100030 applied to the data derived from this arrangement and C248800100031 amounted to less than 4.3% in all cases.
