Comments
Beam quality: no data
Target: A self-supporting Be9 foil of thickness ~100 μg/cm2 with a small amount of gold evaporated onto it.
Data obtained: exported from EXFOR
(By authors) The relative normalization was obtained using the yield of elastically scattered Be-9 from Au-197 recorder by a monitor detector which was placed at 19-degree. Absolute normalization is obtained by normalizing the yields obtained at two or three of the most forward angles (4.5, 6 and 7.5-degree) to the theoretical cross sections obtained from optical model calculations. Normalization procedure plus the statistical counting error, especially at backward angles is approx. 15% in the result at these angles.
