Cohesion in monovalent metals

A first principles pseudopotential calculation of metallic binding is performed via an ansatz previously used successfully in discussing electron transport properties. Without recourse to any experimental data (other than the values of the fundamental constants) a single procedure is found to give energy-volume curves for all eight monovalent metals which are consistent with the observed cohesive energies, lattice parameters and pressure-volume relationships. Though not as accurate as conventional cellular methods, it has the merit of revealing how the electron-ion scattering variations which give the monovalent metals their distinctive transport properties are also responsible, in large measure, for the individual characteristics, from metal to metal, associated with cohesion.
