CommentsBeam quality: The 11 B3+ beam was varied in intensity from 1 to 30 nA depending on the angle Target: The 209 Bi target was 100 mcg/cm2 in thickness ans has been evaporated onto 40 mch/cm2 thick carbon backing foil. Data obtained: author graph (digitized with GSYS 2.4 ) The Oak Ridge isochronous cyclotron was used.
