摘要：

Electronic excitation (dE/dx)(e) due to swift-heavy-ion irradiation induces giant plastic deformation in amorphous solids. In situ electrical resistance experiments performed on Fe-B ribbons irradiated with different tilting angles with respect to the ion beam provide quantitative information about the deformation phenomenon. In particular, dimensional variations occurring in the early stages of the process can be evaluated. At medium (dE/dx)(e) (irradiation with Xe ions) the growth starts with a zero rate within experimental uncertainties, whereas an initial nonzero rate is observed at high (dE/dx)(e) (irradiation with Pb or U ions). Results are discussed in light of a recent model based on irradiation-induced thermal spikes.
