# Molar volume of solid isotopic helium mixtures

@article{Herrero2008MolarVO, title={Molar volume of solid isotopic helium mixtures}, author={C. Herrero}, journal={arXiv: Materials Science}, year={2008} }

Solid isotopic helium mixtures have been studied by path-integral Monte Carlo simulations in the isothermal-isobaric ensemble. This method allowed us to study the molar volume as a function of temperature, pressure, and isotopic composition. At 25 K and 0.2 GPa, the relative difference between molar volumes of isotopically-pure crystals of 3He and 4He is found to be about 3%. This difference decreases under pressure, and for 12 GPa it is smaller than 1%. For isotopically-mixed crystals, a… Expand
