TLDR
In this article, the authors measured the p(15N, αγ)12C nuclear reaction on a number of hydrogen-bearing gases to investigate the bond-dependent Doppler broadening resulting from the motion of the target hydrogen atoms.Abstract:
Excitation curves for the p(15N, αγ)12C nuclear reaction have been measured on a number of hydrogen-bearing gases to investigate the bond-dependent Doppler broadening resulting from the motion of the target hydrogen atoms. Contributions to the resonance width due to the intrinsic width of the resonance, gas-induced beam energy loss and energy straggle, accelerator beam energy spread, and Doppler broadening are considered. Calculations of Doppler broadening based on molecular spectroscopy data are presented.read more

Markus Wilde,Katsuyuki Fukutani +1 more
TL;DR: In this paper, the authors introduce hydrogen depth profiling by nuclear reaction analysis (NRA) via the resonant 1H(15N,αγ)12C reaction as a versatile method for the highly depth-resolved observation of hydrogen (H) at solid surfaces and interfaces.

Hydrogen absorption in oxide-supported palladium nanocrystals
TL;DR: Substantial hydrogen absorption in nanometer-sized palladium crystallites on a thin film alumina support is observed at $90--350\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ under low pressure conditions as discussed by the authors.

Water Entry into Silica Glass During Slow Crack Growth
TL;DR: In this article, it was found that water enters SiO[sub 2] glass during slow crack growth in water, suggesting that the correct strength reduction mechanism of silica glass under stress by water in the environment must involve entry of water into the glass.

Below-surface behavior of hydrogen studied by nuclear reaction analysis
TL;DR: The behavior of hydrogen in the near-surface region can be investigated by a nuclear reaction analysis (NRA) technique as mentioned in this paper, where the H atom adsorbed on a surface might penetrate the surface and in-diffuse toward the bulk.
