The surface densityD008800100014 of the foils ranged between 3 and 8 mg/cm2. Two stacks D008800100015 of 64Ni foils, each containing up to 12 samples. D008800100016 The first stack contained a number of high purity D008800100017 copper foils with the surface densities between 4.3 andD008800100018 4.7 mg/cm2 and a few aluminium foils in the sequences D008800100019 Cu-Ni and Ni-Al. The copper foils served as beam energyD008800100020 absorbers, beam flux monitors and also allowed D008800100021 cx-particle beam energy control along the stack. The D008800100022 aluminium foils were used as beam energy absorbers D008800100023 and catchers of the escaping residual nuclei. D008800100024 The second stack contained aluminium foils inserted D008800100025 between 64Ni foils and a single copper foil was used D008800100026 for the beam current measurement.
