  High electronic excitations in radiation of metallic targets with swift heavy
ion beams at the coulomb barrier play a dominant role in the damaging processes
of some metals. The inelastic thermal spike model was developed to describe
tracks in materials and is applied in this paper to some systems beams/targets
employed recently in some nuclear physics experiments. Taking into account the
experimental conditions and the approved electron-phonon coupling factors, the
results of the calculation enable to interpret the observation of the fast
deformation of some targets.
