Depth resolution of transmission ERDA for H in Al under nuclear-elastically enhanced recoiling of H by 8 MeV He

This manuscript describes our experimental work being carried out to develop the previously published T-ERDA technique to measure H distribution in solids [Yamazaki et al., AIP Adv. 9 (2019) 105111]. From the experiments for the samples with H markers, we have identified the factors that degrade the depth resolution for analysis of H distribution, depending on the acceptance conditions of the detector.
