Characterization of ultra-heavily damaged NaCl

In this paper we present the progress made to (i) characterize the defect state of ultra-heavily damaged rock salt samples with up to more than 20 at% Na colloids, which had been irradiated with 0.5 MeV electrons at 100 ºC up to 10^4 MGy (1000 GRad), and (ii) understand their physical properties. The explanation of the observations, made by means of a variety of experimental techniques, is not trivial and often the results obtained with different experimental techniques lead to conflicting interpretations
