- Activation
- Beam current integrated
- Stacked target irradiation (Samples put on the front of surface
were used for measurements of the reaction cross section and the
mass-yield distributions or produced nuclides, while samples
inserted between the Cu plates were used for measurements of the
spatial distribution of the residual activities of produced
nuclides in copper and of the energy dependence of the cross
section.)
