We report high-resolution infrared absorption spectroscopic studies of the dopant-induced Q₁(0) vibron band in solid parahydrogen crystals doped with low concentrations of rare gas atoms. The frequency, lineshape, and ...

Hydrogen atoms were trapped in a quench condensed Kr matrix and investigated by EPR. Each hyperfine component is a superposition of broad and narrow line. The spectrum of narrow lines shows an axial anisotropy of the ...

The thermal conductivity of solid hydrogen with 1–2 ppm Ne impurity was investigated in the temperature range 1.5–10 K on samples grown from the liquid phase at various growth rates. The result differ qualitatively from ...
