Popis:	The analysis of thermally stimulated current measurements by the use of the RMA method (Relaxation Map Analysis) shows that in a mordenite-type zeolite, sodium ions are localized into three different sites. It is assumed that each RMA peak results from a distribution of relaxation times even though it corresponds to a very narrow domain of temperature. By varying this temperature window, it is thus possible to determine the contribution of each type of sodium to the whole dielectric response of the material. Therefore, the nature of the different Na + /mordenite network interaction can be assessed.
