Electron correlation effects reflected in thermodynamic properties of light actinides

ABSTRACT

Experimentally available thermodynamic data on the light actinides is used to display the ratio from Th through to Cm. Dramatic variation through the series by a factor of 4 contrasts strongly with that found for the five heavy rare earth solids, also involving f-electrons, where the same ratio is approximately 50 to within a few percent.
