Effect of combined local variations in elastic and inelastic energy
losses on the morphology of tracks in ion-irradiated materials

Abstract

A judicious choice of irradiation parameters and experimental methodology allowed the visualization of the tracks created by swift heavy ions in pyrochlores over the entire ion trajectories. Several peculiarities were observed: a layered structure of tracks composed of an amorphous core surrounded by a strained crystalline envelope, a change of the track diameter as a function of the ion slowing down, a loss of parallelism of tracks, a transformation from continuous to discontinuous regime, and an increasing contribution of elastic collisions at large depths. These observations are compared to the respective amount of electronic and nuclear energy losses.
