(a) Pressure dependence of atomic volume of Ce (except γ-Ce). Each phase is fitted by Birch–Murnaghan equation of state fixing The square, circle, and triangle represent α-Ce, α″-Ce, and ε-Ce respectively. (b) The comparison between literature data and the results from this work. The results of experiment on polymorph are fitted to the Murnaghan equation (solid line).
