Ion tracks in pyrochlores

Contemporary investigations of swift heavy ion irradiated A2B2O7 pyrochlores are driven by the interest in their use for the immobilisation of nuclear waste [1, 2]. Employed techniques (X-ray diffraction, transmission electron microscopy, Raman spectroscopy) provide detailed insight into pyrochlore response to fission-fragment like radiation. Here we describe present status in this field and compare experimental results on ion track size and structure against theoretical predictions. [1] R.C. Ewing, W.J. Weber, J. Lian, J. Appl.
