In the present study, in order to understand tritium behavior in solid breeding material Li2TiO3, the X-ray photoelectron spectroscopy （XPS） and thermal desorption spectroscopy （TDS） experiments are carried out to elucidate the trapping behavior using 3 keV D2^＋ implanted sample. The Ti-2p XPS spectrum shows that a shoulder appeared at the lower energy side as increasing ion fluence, and it was suggested that Ti^3＋ was formed by the reduction of Ti^4＋.展开更多
