Using a computer, the Fermi surface for the one‐electron model of an infinite crystal in three dimensions with zero range interactions, i.e., with so‐called point interactions, is studied. A computer program is available which has, as input, the crystal structure, the scattering length of the solid considered, and the Fermi energy, and, as output, a drawing of the corresponding Fermi surface inside its Brillouin zone.
