摘要：

The band-structure of one-dimensional Schrödinger operators is calculated when there are (a) high potential barriers (or deep wells), or (b) a wide lattice-spacing (i.e., the distance between minima of the potential). Explicit power-series formulae and error estimates are rigorously proved. The procedure used, a rigorous semi-classical method, is actually convergent for nonzero scaling parameters. Some general facts about the spectra are also discussed. © 1979.
