High pressure X-ray diffraction experiments on NpS and PuS up to 60 GPa
Neptunium and plutonium monosulfides were studied under high pressure up to approximately 60 GPa using a diamond anvil cell in an energy dispersive X-ray diffraction facility. The compounds, of cubic rock salt structure type at ambient pressure, do not show any crystallographic phase transition in the domain of investigation. From the pressure-volume relationship, bulk moduli of 92 GPa and 120 GPa were determined with pressure derivatives of 4.6 and 4.1 NpS and PuS respectively.
