Reactions of Bromine Activated by Bromine−82m Isomeric Transition and Radiative Neutron Capture in Liquid and Solid Carbon Tetrachloride and n-Hexane

Abstract

New methods have been developed for obtaining ⁸²Br and ⁸²Br^m organic retentions produced by ⁸²Br^m isomeric‐transition reactions and radiative neutron capture by ⁸¹Br, respectively. No isotope effect was found for ⁸⁰Br^m and ⁸²Br^m reactions activated by the (n, γ) process. The ⁸²Br^m (I.T.) ⁸²Br process was found to produce ⁸²Br organic retentions nearly twice as high as the ⁸⁰Br^m and ⁸²Br^m organic retentions produced by the (n, γ) process. Effects of solidifying samples indicate a clumping of bromine molecules upon freezing. Product analyses indicate similar reaction mechanisms for the (n, γ) and (I.T.) activated reactions.
