The volume change of cerium metal at the α→α′ phase transformation at 51 kbar is found to be (1.5±1) % from macroscopic measurements made in the sliding‐anvil apparatus SAD 2. This value supports the proposal by Zachiarasen and Ellinger that the high‐pressure forms of cerium above 51 kbar are a stable orthorhombic form with the α‐uranium type of structure and a metastable monoclinic body‐centered form with a deformed face‐centered structure and invalidate all the other crystal structures reported so far for α′‐cerium.
