Abstract

In order to obtain 3D mapping of the hydrogen distribution in solids in-situ, the nuclear reaction analysis (NRA) measurement has been carried out by using a tapered glass capillary to focus and introduce the incidence beam to the sample under atmosphere. A Y thin film covered with Pd was used for this measurement. In the N₂ gas, hydrogen absorbed by the Y film was observed at a pressure up to 8 × 10³ Pa. In the H₂ gas and air, on the other hand, substantial γ-ray signals were observed at ¹⁵N energies of 6400∼7200 keV, which obscured the signal originating from the Y sample. The origin of this signal is discussed.
