Damage rates and recovery of 99.99% pure tungsten have been investigated after electron irradiation near 4 ° K by means of electrical resistivity. The damage rate data tend to a value of T 0 = 38 to 42 eV. The recovery of the residual electrical resistivity shows three major stages: Stage I from 4.2 to 100 ° K, Stage II from 100 to 500 ° K, Stage III from 500 to 1000 ° K. Stage I is dominated by only one major peak at 70 ° K. An analysis based on second‐order kinetics yielded a good fit to the data through 95% of the recovery. The energy derived was 0.17 eV. Only ≈ 26% recovery is seen in Stage I and we propose that the suppression is due to interstitial trapping by impurities. Stage III accounts for about 40% recovery of the induced resistivity and has a center temperature of 760 ° K. The stage was analysed assuming second‐order kinetics; this analysis gave an energy of 1.1 eV.
