摘要：
This article describes the authors' use of the Weiss two-state model for Fe-Ni invar alloys to understand the anomalous thermal expansion of Pu-Ga alloys. Studies on thermal expansion of Pu-Ga are reviewed briefly, and the two-state invar model is described. The authors fit the available neutron-diffraction data for Pu-Ga alloys to the invar model and discuss the consequences.
