Title: The thermal expansion of pure metals and the possibility of negative coefficients of volume expansion
Abstract: The dominant factors controlling the volume thermal expansion of solids are discussed. It is shown that if the Fermi energy of the electron gas has a value for which the density of states of the electrons changes sufficiently rapidly with energy, a negative coefficient of volume expansion may reasonably be expected, particularly if this is associated with a high electronic specific heat from a large number of overlapping bands. It is suggested that this is the reason underlying the observed negative coefficient of volume expansion of the cubic phase in plutonium.
