Energetic ¹²⁸I reactions in Cdl₂ - H₂O system

Energetic ¹²⁸I reactions in gaseous and liquid phase are studied extensively by conventional retention measurements. Also a few charge plate collection experiments in liquid phase are performed. However, hot iodine atom reaction studies in water at N.T.P. by charge plate collection experiments are not reported so far. The present effort is an attempt to study the reactions of energetic ¹²⁸I atoms originating from neutron bombardment of cadmium iodide in water. It is hoped that a relatively high thermal neutron capture cross section of iodine and convenient half life of ¹²⁸I enable us to study favorably the high energy chemistry following ¹²⁷I(n,γ)¹²⁸I reaction in water. Present results are new and are critically discussed with the existing views, theories and mechanisms. It is concluded from the present investigation that the reactions of energetic iodine species in CdI₂-H₂O system is essentially governed by the reactivity of medium principally with the formation of reaction intermediates and/or complexes through collapsing the original molecular environment
