• Radiation annealing by 100 MeV "'I-ions is studied in pre-doped Ni and Cusamples through the defect production rate measurements below IOK. The experimental results are analyzed by using a new model which describes the productionand radiation annealing of two or more types of defects. The sttbthreshold recombination cross section and the concentration of doped-in defects are obtained for eachtype of defects. In Ni, the defect annihilation corresponding to the stage-l thermal an-nealing occurs during the I-ion irradiation with the subthreshold recombination crosssection of 6.5 X 10 " to 1.4 X 10 "cm'. In Cu, the stage-I defects are annihilatedwith the cross section of 4.6 X 10 " cm'. The large radiation annealing in Ni showsthe contribution of the electron excitation by irradiating ions to the subthresholdrecombination of defects thrc>ugh the electron-phonon interaction.[radiation annealing, nickel and copper, electronic excitation, electron-phonon ll interactionl
