反跳粒子検出(ERD)法及び中性子ラジオグラフィー(NRG)法により、チタン水素化物(TiHx: x=1.65~1.96)の水素濃度を測定した。ERD法ではTiHx表面(約0.3mm),NRG法ではTiHxバルクの水素濃度を$$Delta$$x=$$pm$$0.05程度の精度で測定可能であり、各水素分析手法の有効性を確認した。

Practicability of Elastic Recoil Detection (ERD) and Neutron Radiography (NRG) methods for hydrogen concentration in titanium hydrides (d-TiHx : 1.6<x<2.0) is investigated. In ERD methods, the hydrogen concentration in the surface of TiHx is recognized. In NRG method, the hydrogen concentration over the balk was confirmed. These results show that both methods are effective means for estimating the hydrogen concentration in hydride materials.
