Abstract

High-pressure X-ray diffraction studies were performed at room temperature on a uranium-neptunium binary alloy, using a diamond anvil cell in an energy dispersive facility. The sample maintained its simple cubic phase up to 62 GPa (highest pressure reached in this experiment). The bulk modulus and its pressure derivative were determined to be B(0)=82(2) GPa and B'(0)=9.4(1.3), from the experimental data in the pressure range 0-20 GPa. The results are compared with those obtained for uranium and neptunium.
