Abstract
The influence of the radial energy distribution on the formation of io n tracks is investigated by track etching in amorphous metallic Fe81B1 3.5Si3.5C2. An etching threshold of almost 4 keV/Angstrom is observed for high energy ions (Au, 35 MeV/u), which is slightly higher than the threshold of 3.6 keV/Angstrom of low energy ions (Xe, 6.1 MeV/u). In the frame of the thermal-spike model, the track radius is calculated a s a function of the ion energy loss. For a given energy loss, the mode l predicts a small increase of the etching threshold as a function of the ion energy, in agreement with the experimental results.
