Beam quality: The Koln 10 MV Van de Graaff Tandem provides 6Li3+ beams of 40-50 nA. The Bochum Tandem provides 6Li beams of 20-40 nA.
Target: A metalic target of mixed composition of 7Li (22.5 μg/cm2) and 6Li (40 μg/cm2) on carbon backings of 20 μg/cm2 (for the Koln experiments). A natural Li target (92.5% of 7Li (13.5 μg/cm2) and 7.5% of 6Li) on carbon backings of 10 μg/cm2 (for the Bochum experiments).
Data obtained: author graph (digitized with GSYS 2.4)
First experiment (Elab = 9-16 MeV) was carried out at the Dynamitron-Tandem Laboratorium at Ruhr-Universitat Bochum. Second experiment (Elab = 20-40 MeV) was carried out at the 10 MV Van de Graaff Tandem at the Koln Tandem.
