Pre-heat treatment study of recoil 128I in lithium and copper iodates

Abstract

The effect of pre-heat treatment on the (n, γ) reaction of LiIO₃ and Cu(IO₃)₂ targets is an increase in the initial retention in Cu(IO₃)₂ and decrease in LiIO₃. This has been ascribed to the competitive participation of oxidizing and reducing inherent crystal defects. Annealing kinetic studies reveal two apparent first-order processes for both the pre-heated and untreated iodates. An exciton mechanism is proposed to explain the higher plateau values and annealing kinetics in pre-heated Cu(IO₃)₂ and LiIO₃.
