Summary form only given. The authors have applied self-consistent relativistic band theory based on the local spin density functional formalism to the series of actinide metals Fr-Cm, Lw. They present as functions of atomic volume and atomic number the calculated partial electronic pressures, the bulk moduli, the partial occupation numbers, and the partial state densities, and show the derived lattice spacing as a function of the atomic number. They discuss the fundamental question of itinerant versus localized behavior of the 5f electrons in terms of the effect of spin-polarization on the partial pressures.
