TRANSIENT FIELD-MEASUREMENTS ON FE-56-ION AND SE-80-ION USING SEGMENTED FE-LAYERS

Measurements of transient magnetic fields (TF) were performed on swift heavy ions of Fe-56 and Se-80, with Coulomb excitation of their first 2(+) state as probe, traversing thin Fe layers with segmented and uns egmented structures. The 50 mu m x 50 mu m squares of the segments wer e accomplished applying the techniques of photolithography and ion etc hing. The magnitude of the TF deduced clearly shows that by segmentati on of the targets the ion beam induced attenuations can be eliminated. This finding has direct applications to g-factor measurements.
