Phase diagram

The phase diagram for temperatures in the range of 17–50 K and pressures between 10⁻² and 2×10³ bar has been calculated in Ref. 4. The critical point was located at $T_{c}=46.7~{\mathrm {K} }$ and $p_{c}=27.7$ bar (Ref. 4 Table I), and the triple point at $T_{tp}=24.55~{\mathrm {K} }$ and $p_{tp}=0.315$ bar (Ref. 4 Table II).
