@article{Chase1973MeasurementOR, title={Measurement ofP-V-T relations and critical indices of3He}, author={C. E. Chase and George O. Zimmerman}, journal={Journal of Low Temperature Physics}, year={1973}, volume={11}, pages={551-579} }

By measuring the capacitance of a parallel-plate capacitor filled with3He as a function of temperature and pressure, we have determined the dielectric constant of3He along 28 isotherms between 3.00 and 3.45 K at pressures up to 103 Torr, and along the coexistence curve between 3.20 K and the critical temperature for both saturated liquid and vapor. The density along these same trajectories can then be calculated assuming the Clausius-Mossotti relation holds. We have evaluated the critical… Expand
