Abstract With a series of supportive experimental phenomena as induced by ion beam bombardment, energetic beam-induced athermal activation process in Si is demonstrated. This is correlated with phenomena induced by
ultrafast energy exchange in condensed matter in general. A critical modelling is presented on the above process and a universal concept: the ultrafast energy exchange-induced soft mode of phonons and the lattice
