The resistivity annealing spectrum from 8 to 51 c- K of the damage produced by a flux of 7.5 x 10/sup 17/ 3-Mev electrons/ cm/sub 2/ on 99.999% pure gold and cadmium was studied. The total damage and residual resistivity for gold was 8.5 x 10/sup -9/ and 3 x 10/sup -9/ ohm-cm, and for cadmium 2.32 x 10/sup -9/ and 5.3 x 10/sup -9/ ohm-cm respectively. The gold activation energy spectrum was derived directly from the isothermal annealing curves. The spectrum consists of at least nine peaks, with 22% of the damage annealing out up to 51 c- K. These results confirm earlier suggestions that the radiation damage in gold is basically different from that of copper and silver. In connection with the amount of low-temperature annealing, it is thought that focussing and interstitial clustering is important. Deviations from Mathiesson's rule for gold and cadmium are in qualitative agreement with theory. Only qualitative agreement with an earlier experiment on the annealing of cadmium can be confirmed.
