The reactions of <SUP>125</SUP>I obtained from the <SUP>125</SUP>Xe(EC)<SUP>125</SUP>I process with methane have been investigated. It was confirmed that electron scavengers, such as I<SUB>2</SUB>, SF<SUB>6</SUB>, and O<SUB>2</SUB>, play an important role. The main product is only CH<SUB>3</SUB><SUP>125</SUP>I, the yield decreasing significantly with the concentration of Xe. By adding various additives, the yield of CH<SUB>3</SUB><SUP>125</SUP>I in the presence of trace amount of I<SUB>2</SUB> was assigned as follows: 8.7±6.7% by the hot atom reaction, 35.8±8.0% by <SUP>125</SUP>I<SUP>+</SUP> in the <SUP>1</SUP>D<SUB>2</SUB> state, and 31.5±2.0% by <SUP>125</SUP>I<SUP>+</SUP> in the <SUP>3</SUP>P states. The results are discussed in comparison with those reported on similar reactions utilizing different activation processes. Chemical sequences of the formation of CH<SUB>3</SUB><SUP>125</SUP>I are proposed.
