Electron irradiation (2 MeV, up to 6 x 10$sup 18$ e/cm$sup 2$) decreased the yield stress of iron single crystals in the temperature range from 4.2 to 80$sup 0$K. The softening effect was highly dependent on the tensile axis orientation. The temperature and strain rate dependency of the yield stress was increased by the irradiation. The annealing of the softening took place between 90 and 150$sup 0$K. The observation is consistent with an intrinsic solid solution softening mechanism based on the enhancement of screw dislocation motion due to dispersed interstitials. (auth)
