Abstract
A discussion is given of the cellular method and the various sources of error in it. Numerical examples show that the method is practicable and that it provides accurate and unambiguous energy eigenvalues, subject, like in other methods, to the validity of the spherical approximation to the potential, which is discussed. An interpolation scheme for the bands is given. Methods to obtain the density-of-states curves, Fermi energies and Fermi surfaces are given and illustrated with some results for Be metal.Keywords
