The results of attempting to fit the step‐annealing data to an activation energy distribution indicate a dispersion of the frequency factor ranging from 107to 1011sec−1which is explained as arising from diffusion processes. The distribution appears to rise gradually to a peak with the possible existence of a subsidiary peak, then a very sharp drop from the peak. This sharp drop indicates the annealing processes are first order. The beginning of the distribution is in accord with its being the residue from annealing during bombardment, subsequent treatment, and storage. It is hypothesized that the gradual rise is associated with the dispersion of the frequency factor.
