Solid solutions of U x Th 1− x Se for x = 1.00 ÷ 0.80 and the solid solutions of U x Y 1− x Se for x = 1.00 ÷ 0.60 were studied by the X‐ray diffraction over the temperature range 100 ÷ 200 K. In both systems rhombohedral distortions of the cubic rock‐salt crystal structure was observed below the Curie temperatures. The temperature and composition dependences of the rhombohedral angle ω of the rhomboedral cell and the \documentclass{article}\pagestyle{empty}\begin{document}$ \frac{{c' - a'}}{{a'}} $\end{document} ratio were determined.
