    • Reference [5] treats radiation-induced defects detected by electron spin resonance in bulk NaPO3 and Ca(PO)23 glasses and reports dose-dependent recovery rates potentially interpretable by the present theory. Although the authors of Ref. [5] described their growth curves as having an initial ``linear dose dependence,'' the straight-line slopes scaled from the illustrated log-log plots were f = 0.85 and 0.75 for the respective glasses, i.e., they were power laws.

    • An explicit case can also be made for the inherently natural presumption of second-order kinetics: Inspection of the model solutions of Fig. 1 reveals that the assumption of n = 1 implies f to be independent of D dot (and C propḊ), whereas the experimental data of Fig. 2(a) show more complex behavior, with $f decreasing with increasing D dot.

    • The roller-coaster natures of the predicted curves result from the crude approximation of using just three subpopulation components, corresponding to the nominal mean Ki value, Kmean, plus the components 3 Kmean and (1/3) Kmean.

    • The present analysis correctly predicted the half-life [tau in Eq. (10)] in all cases except for the highest-dose-rate data of Fig. 2. The factor-of-2 discrepancy between the experimental and predicted values of tau evident in Fig. 4 (squares) is tentatively ascribed to the continuous curvature (as opposed to straight-line behavior) manifested in the corresponding log-log growth curve of Fig. 2(a).
