Abstract
The excess pressure due to phase separation of solid ${\mathrm{He}}^{3}$-${\mathrm{He}}^{4}$ mixtures held at constant volume has been measured. From this we obtain the phase-separation temperature as a function of the mole fraction, the excess volume, and the pressure dependence of the critical temperature.
