Radiation damage in NaCI : the process of colloid formation

The measurements of the melting transition of the sodium colloids presented in chapter 6 can be considered as the central part of this thesis. They provide us not only with information about the amount of sodium and chlorine formed in the crystal, but also with detailed information about differences between high and low dose irradiated crystals, between different irradiation temperatures and between the situation before and after performing other experimental methods. We have analysed many NaCl crystals irradiated with doses between 5 and 150 Grad with this method, in order to obtain insight in the development of the formation of sodium colloids. The differences in the behaviour of Li doped crystals and K doped crystal is striking: while the amount of damage (precipitated sodium and chlorine) in Li doped crystals saturates at about 1%, in K doped crystals the formation of radiation damage does not stop. ...
