High-purity Al and the alloy Al-15 ppm Ag have been irradiated with electrons at liquid-helium temperatures. The influence of various parameters (electron energy and dose, impurity content and the, presence of excess vacancies introduced by prequenching or irradiation doping) upon the annealing spectra of the radiation-induced residual electrical resistivity was determined. Besides the usually observed recovery substages in stage I ( I/subB/, I/subC/, I/subD/, and I/subE/), several supplementary structures were found labeled I/subA/ (at 14 to 15$sup 0$K), I/subC//sup prime/ (at 26 to 27$sup 0$K), I/subD//sup prime/ (at 33 K), I/subD//sup double-prime/ (at 39$sup 0$K), and I/subF/ (between 53 and 59$sup 0$K). The observed characteristics are compatible with the attribution of the substages I/subA/, I/subB/, I/subC/', and I/subC/ to close-pair recombination; I/subD/', I/subD/, and I/subD/'' to correlated migration of interstitials; I/subE/ to the recombination of freely migrating interstitials; and I/subF/ to the migration of diinterstitials.
