Survival Probability of Products of Hot Reactions of (n, γ)-Produced 38Cl with CH3Cl in the Gas Phase

The hot reactions of (n, γ)‐produced ³⁸Cl with CH₃Cl have been studied in the presence of three noblegas moderators: He, Ar, and Kr, using Br₂ as a scavenger. The main purpose of this work was to study the extent of decomposition of the newly formed products upon collision with Ar and Kr. Applying the method of Baer and Amiel, it was established that the average survival probability of the various hot products in Ar and Kr is 100%, within the experimental error. Kinetic parameters for the three hot products, ${\mathrm{CH}}_3^{38}\mathrm{Cl}$ , CH₂Cl³⁸Cl, and ${\mathrm{CH}}_2^{38}\mathrm{ClBr}$ were determined as well.
