The permeability was determined by firstly ion-implanting reactive O sinks, and then using the nuclear reaction, D(3He,p)4He, to monitor D accumulation in the sinks during D2 exposure. Results were obtained for temperatures of between 573 and 373K (table 10). Previous measurements of the lattice permeability, made using standard foil permeation methods, extended down to only 523K. Therefore, the present study expanded the then-existing range of available permeability data by 5 orders of magnitude. Standard foil permeation experiments were also carried out at temperatures ranging from 688 to 768K, in order to permit comparison with earlier work. When combined with previously published data, the results indicated that the permeability of D in Au exhibited an Arrhenius temperature dependence over 10 orders of magnitude and at temperatures ranging from 373 to 913K.
