    We studied the recombination-enhanced Fe atom jump between the first (1st) and second (2nd) neighbor sites of Fe-Al and Fe-B pairs in Si. We first annealed specimens at 80 °C to generate Fe-acceptor pairs after doping of Fe. Concentrations of the 1st and 2nd neighbor Fe-acceptor pairs were determined by electron-spin-resonance (ESR) measurement after annealing at around 150 K under optical excitation. The concentration of the 1st neighbor pair was decreased and that of the 2nd neighbor pair was increased by the above annealing. Activation energy for the above changes was about 0.11 eV in the case of the Fe-Al pair. This is much smaller than that (0.8 eV) of thermal annealing alone. In the case of the Fe-B pair, the ESR signal of the 2nd neighbor pair could be detected due to annealing at around 160 K under optical excitation.
