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