Phase diagram and critical points of Ce alloys.

The pressure-temperature phase diagram of Ce(0.9-x)La(x)Th (0.10) alloys is presented for 0.1 = x = 0.17. Two critical points are found in this range of compositions. The data are shown to be consistent with an analysis based on the known Fermi-liquid behavior of Ce in compounds and alloys. The possible appearance of beta-phase at intermediate pressures is noted.
