CommentsBeam quality: intensities of 10—100 nA Target: Isotopically enriched targets (except for Si) of thickness's ranging from 11 to 33 mg/cm2 were used Data obtained: author graph (digitized with GSYS 2.4 ) The Li beams were provided by the Indiana University Cyclotron Facility (IUCF). Usable intensities of 10—100 nA (electrical) at 99 MeV were achieved by accelerating Li++ ions through the injector cyclotron and, after further electron stripping, accelerating the bare Li ions in the mainstage cyclotron to full energy. Absolute errors are estimated to be +12%, and are due largely to target thickness uncertainties.
