Effect of Inert-Gas Moderators on the (n, γ) Activated Reaction of I128 with CH4

Abstract: In the presence of a large excess of gaseous methane, 54.4±0.5% of p28 formed by (n, 'Y) activation was found to become stabilized in organic combination. The effects of inert-gas additives in moderating the reaction of Il28 with CH. were determined in an effort to ascertain the mechanism. The data, extrapolated to zero mole-fraction methane, indicate that xenon is capable of reducing the organic 1 128 to 11% whereas neon, argon, and krypton each reduce it to only about 36%. These data suggest that of the 54.4… Show more

“…To verify this theoretical plot, we determined experimentally a number of scavenger curves for bromoform-benzene mixtures of different composi-32. It is immediatly obvious that the second order terms are small for systems of low reactivity [15,16].…”

“…Without assuming any model for the reaction mechanisms, they developed a purely kinetic theory for hot atom reactions in gaseous media. The theory was successfuUy applied to systems containing hot hydrogen [13,14], bromine [15] and iodine [16] atoms. The use of such a simple kinetic treatment to hot reactions in liquid media is not immediately obvious.…”
