It is the purpose of the present paper to describe crystal structure determination of Pu2C3 in some detail. In the preliminary account of the investigation the identification of Pu2C3 was given as tentative in character. The uncertainty of the identification was later removed, and the identity is, of course, further confirmed by the recent identification of a corresponding uranium compound.

The high-temperature enthalpies of plutonium monocarbide and plutonium sesquicarbide have been determined with a copper-block calorimeter of the isoperibol type. The experimental enthalpy data, which was measured relative to 298 K, covered the temperature range from 400 to 1500 K. The calculation of the temperature rise of the calorimeter takes into account the added heat evolution from the radioactive decay of the plutonium samples. These enthalpy results, combined with the heat capacity and entropy of the respective carbide at 298 K available from the literature, has made it possible to generate tables of thermodynamic functions for the plutonium carbides. The behavior of the heat capacity of both of the plutonium carbides, i.e., a relatively steep increase in the heat capacity as the temperature increases, may be attributed to a premelting effect with the formation of vacancies within the crystal lattice although a theoretical treatment of this phenomenon is not given.

Actinides in Perspective presents in proceedings of the Actinides-1981 Conference held in Pacific Grove, California, USA on September 10-15, 1981. The book contains papers on the different aspect of the physics and chemistry of the actinides. The text includes papers on the history of the discovery of the transplutonium elements; the photoemission techniques; and the neutron scattering studies of the actinides. The new elements in the transfermium region; the isotope identification in the transfermium region by ?-? correlation after in-flight-separation; and the fission properties of the actinides are also considered. The book further tackles papers on the status of superheavy element research; the single crystal preparation of actinides and actinide compounds; and the preparation of transplutonium metals and compounds, protactinium metal and compounds, and actinide metals. The text also includes papers on the complex oxide systems of the actinides; thermodynamic properties of the actinides; and the chemical and physicochemical properties of actinide organometallic compounds.
