Abstrakt: We present a Grüneisen analysis of the intriguing temperature dependence of the thermal expansion and bulk modulus of delta phase plutonium alloys. This analysis exploits the thermodynamic relationship between these quantities and the heat capacity and reduces the description of complicated behaviour to the determination of a manageable number of numerical constants. We conclude from the analysis (1) that there is a small Schottky-like heat capacity anomaly at high temperatures and (2) that the size of this anomaly depends strongly on alloy concentration. Grüneisen analysis provides an economical description of the thermal expansion and bulk modulus of?-Pu. [ABSTRACT FROM AUTHOR]
