摘要：
It is well known that under swift heavy ion irradiation Vitreous silica is subject to compaction as well as to plastic flow. The aim of this contribution is to demonstrate that both phenomena can be understood on the basis of the thermal spike concept and the fact that molten silica exhibits a density anomaly in the temperature range between 2000 and about 5000 K. It is found that the predicted values for ion-beam-induced compaction and the growth-rate for plastic flow are in reasonable agreement with the experimental data obtained previously.
