Abstract

The critical density

ρ_{c}

of Xe has been determined by two independent methods. The first value, 1.1128 ± 0.0003 g/

{cm}^{3}

, is based on coexistence-curve data and extrapolation to the critical temperature using the "law of rectilinear diameter." The second method, based on critical-isotherm data and an analysis of gravitational effects, reveals no deviation of the diameter from linearity within the limits of error. If

ρ_{c}

differs from the extrapolated value, the difference is less than 0.5%.
