Abstract
The chemical behavior of 115Cd recoil atoms was studied in cadmium phthalocyanine which had been subjected to pre-irradiation treatments such as quenching, irradiation with γ-rays, or irradiation in a nuclear reactor. It was found that the initial retention of the quenched sample was smaller than that of the untreated sample, and that the difference between the initial and the plateau retention, ΔR, increased when the sample had been quenched from 190°C. Only a small change in the behavior of the recoil atoms was observed in both cases of irradiation prior to the recoil reaction. The results are discussed in terms of the defects; the central metal vacancies introduced in the complex by quenching has a big effect on the subsequent course of the thermal annealing reaction.
