Hydrogen profiles at the surface of leached Synroc [Authors' reply to ‘Comments on the paper by Hj. Matzke et al., Nucl. Instrum. Meth. B45 (1990) 194’]

Abstract Heavy water, D 2 O, was used in the preceding paper by Dytlewski et al. in a leaching experiment of the Australian titanate waste ceramic Synroc. The results were compared to previous data with H 2 O of the present authors. The leaching experiment in H 2 O was now repeated confirming the previous results. The small differences in these two types of experiments and the relevant features of the elastic recoil detection analysis, ERDA, are discussed.
