| Research Abstract |
Aging process of self-radiation damage in minor actinide dioxides has been investigated microscopically by means of 17O NMR. In 243AmO2, we have observed a rapid change of the NMR line shape over the short time interval of one month. The result demonstrates that the self-radiation damage rapidly increases the numbers of defect at low temperatures, and further, that the electronic ground state of the system is highly sensitive to the disorder. The NMR data have also revealed short-range, spin-glass-like character for the magnetic transition in this system.
