Abstract

The radiation damage was studied on ~(111)In nuclei recoil implanted inAg following ~(109)Ag(α,2n)~(111)In reaction by TDPAC method. The Ag foils(20μm) wereirradiated with 30MeV α particles under room temperature, the particle dose ratebeing 4.2×10~(12)cm~(-2)s~(-1). The experimental results indicated that the radiation damagewas severe in Ag even at room temperature. An electric field gradient of 10~(18) V/cm~2which is due to the radiation damage has been put onto the ~(111)Cd probe. The cubic Ag lattice was destroyed and lots of vacancies and interstitials cre-ated in Ag by radiation. The divacancy trapping has been suggested and the laserannealing has been conducted.

Key words: radiation damage laser annealing ~(111)In time differential perturbation angle correlation (TDPAC)
