Comments
Beam quality: +-2 MeV
Target: stacks of gold and aluminium foils and copper degraders between them
Detected particles: gamma-rays of EvR
Data obtained: author's table
The irradiations were performed using the external beam of the Jülich isochronous cyclotron JULIC with alpha-particle energies up to 170 MeV and beam currents of about 80 μA. The radioactive decay of the residual nuclei was followed using conventional Ge(Li) 7-spectrometers. Generally the errors are estimated to be 12-15%, and amount to 20-25% for the most unfavourable cases. The (alpha, pxn) excitation functions were measured separately. In these cases the absolute errors are estimated to be approximately 8%.
