Single-crystal x-ray diffraction has been performed on solid $^{4}\mathrm{He}$ from 1 to 58 GPa over the temperature range 46--400 K. The high-density properties of helium are pinned down: the hcp structure is stable apart from an fcc loop along melt

Measurements of the undercooling temperature of crystallization of 3 He, 4 He, and Ne fluids show that there exists a temperature T a along the melting curve of each system below which no undercooling is observed and above which the undercooling temp

The vibron peak of the ${\mathrm{H}}_{2}$ molecule diluted in helium, neon, argon, and deuterium host systems have been measured up to 40 GPa by Raman scattering. A blue shift of the vibron frequency is observed in all these systems. The line shape o

The vibron frequencies of H 2 and D 2 molecules compressed in a Ne matrix have been measured up to 45 GPa in a diamond-anvil cell. This evolution with pressure is seen to be very different from that measured previously in pure H 2 and D 2 solids: The

A new design for a diamond anvil cell is described. Its main characteristic is that the force on the piston is generated by pressurized helium. Two of its main qualities are illustrated on recent m...

The isotopic shift in the melting curve of He has been measured between 70 and 260 K. An exponential divergence from accurate path-integral Monte Carlo calculations is observed which leads to an opposite isotopic shift above 200 K. The same measureme
