Beam quality: no data Target: Target 116,120Sn with isotopic purity better tan 95% were prepared by vacuum evaporation of metallic Sn, or Sn2O3 reduced with titanium powder, from a niobium boat onto 20 mcg/cm2 carbon backing. Tin thicknesses of about 40mcg/cm2 were used. Data obtained: author's graph digitizedFor most of the runs statistical errors were less than 5%.
