Abstract In the standard treatment of weak-coupling superconductors, the pair potential enters as a nondiagonal but local potential. It is shown that for a pure, weak-coupling, bulk, single-crystal superconductor the quasiparticle wave functions are then Bloch functions and the self-consistent pair potential is periodic in space with the periodicity of the crystal structure. The relation between this periodic character of the pair potential and energy gap structure is discussed, and it is pointed out that energy gap structure of the general character expected appears to have been observed. The validity of a local pair potential is also briefly considered.
