“…For analysis of hydrogen in thin self-supporting samples, a useful method is ERDA of transmission layout (T-ERDA), in which recoil H resulting from hard collisions with He or heavier projectiles is energy-analyzed in the direction close to 0 • after passing through the sample. For example, Tirira and coworkers carried out profiling of H in thin self-supporting samples by T-ERDA using 2-3 MeV He [8] [9]. At about the same time, elastic recoil coincidence spectroscopy (ERCS), which is a variation of T-ERDA, has been developed [10].…”

Hydrogen number densities in thin self-supporting samples of polyphenylene sulfide and muscovite have been determined by nuclear-elastic recoil detection analysis of transmission layout. The analysis procedure is based only on the database of stopping power and recoil cross section for material analysis, without using any reference sample of known H content. For the polyphenylene sulfide sample, the determined value of (2.87 ± 0.26) × 10 22 H/cm 3 is in good agreement with the calculated value of 3.01 × 10 22 H/cm 3 . For the muscovite sample, the H density originating each from bound water and absorbed water is uniform over the entire thickness of the sample. The determined density (9.43 ± 0.75) × 10 21 H/cm 3 of the muscovite agrees excellently with the value of 9.36 × 10 21 H/cm 3 obtained from other quantitative analyses typically applied for minerals. The present results demonstrate the capability of accurate determination of H contents in materials and minerals by transmission ERDA.

Hydrogen concentrations in thin self-supporting samples of polyphenylene sulfide and muscovite have been determined by nuclear-elastic recoil detection analysis of transmission layout. The analysis procedure is based only on the database of stopping power and recoil cross section for material analysis, without using any reference sample of known H content. For the polyphenylene sulfide sample, the determined value of $(2.87\pm 0.26)\times 10^{22}\,{\rm H}/$cm$^{3}$ is in good agreement with the calculated value of $3.01 \times 10^{22}\,{\rm H}/$cm$^{3}$. For the muscovite sample, the H concentration originating each from bound water and absorbed water is uniform over the entire thickness of the sample. The determined concentration $(9.43 \pm 0.75) \times 10^{21}$ H$/$cm$^{3}$ of the muscovite agrees excellently with the value of $9.36 \times 10^{21}$ H$/$cm$^{3}$ obtained from other quantitative analyses typically applied for minerals.

“…Several techniques for quantitative hydrogen imaging have been developed. [1][2][3][4][5][6] However, imaging of hydrogen on a micrometer scale or even with resolutions better than a micrometer is a great challenge. Standard techniques for elemental analyses like x-ray fluorescence or Auger electron spectroscopy 7 are not applicable for hydrogen detection as a matter of principle.…”

“…It is nearly constant for scattering angles between 30°and 60°͑ e.g., lab Ϸ0.1ϫ10 Ϫ24 cm 2 /sr in the laboratory system for 19.8 MeV protons͒ 17 and about three orders of magnitude enhanced over the scattering cross section which would be expected from a pure Coulomb interaction. It has therefore by far the largest ratio of detection cross section to damage cross section of all other possible ion beam techniques for hydrogen analyses like elastic recoil detection 4,5,18 or nuclear reaction analysis. 19 Thus, it is the only technique which guarantees low enough beam damage that hydrogen images of submicron resolution can be gained without significantly changing the hydrogen content in the investigated area.…”

It is a challenge to measure two-dimensional or three-dimensional ͑3D͒ hydrogen profiles on a micrometer scale. Quantitative hydrogen analyses of micrometer resolution are demonstrated utilizing proton-proton scattering at a high-energy proton microprobe. It has more than an-order-of-magnitude better position resolution and in addition higher sensitivity than any other technique for 3D hydrogen analyses. This type of hydrogen imaging opens plenty room to characterize microstructured materials, and semiconductor devices or objects in microbiology. The first hydrogen image obtained with a 10 MeV proton microprobe shows the hydrogen distribution of the microcapillary system being present in the wing of a mayfly and demonstrates the potential of the method.
