• The Estrup-Wolfgang Kinetic theory has been applied to the results obtained from the reactions of <SUP>80</SUP>Br activated by the (n,γ) process with two methanes, CH<SUB>4</SUB> and CD<SUB>4</SUB>. With suitable assumptions, the most probable kinetic parameters, <I>I</I>'s and α's have been obtained. The thermal yields of the products have been estimated as a function of the m.f. of the Kr moderator as the differences between the yields predicted by the kinetic theory with these kinetic parameters and those experimentally obtained. The thermal CH<SUB>3</SUB><SUP>80</SUP>Br and CD<SUB>3</SUB><SUP>80</SUP>Br yields are strongly affected by the m.f. of Kr in such a way that they are not important in the range from zero to around 0.7 m.f. of Kr, but become significant over 0.7 m.f. of Kr. On the other hand, the thermal CH<SUB>2</SUB><SUP>80</SUP>BrBr and CD<SUB>2</SUB><SUP>80</SUP>BrBr yields are much less sensitive to the m.f. of Kr and are almost constant at 0.5% over the whole moderator range of Kr.
