Description

High purity neptunium metal was studied under high pressure using a diamond anvil cell in an energy dispersive X-ray facility. No phase transition was observed up to 52 GPa. A bulk modulus B0=118 GPa and its pressure derivative B'0=6.6 were calculated by fitting the V(P) data to the Birch and Murnaghan equations. The results are discussed in the context of recent compressibility measurements of other actinides. (orig.)
