Surface states in crystals
TLDR
In this paper, it was shown that if the potential is real and (for convenience) symmetric, then if E is not V everywhere in the unit cell, there are no band crossings, and hence no Shockley levels.About:

Ionic, Covalent, and Metallic Surface States of a One-Dimensional Mathieu Potential with Arbitrary Termination
TL;DR: In this paper, a model of surface states on a one-dimensional crystal with sinusoidal potential has been simply solved for arbitrary values of the sinusoid amplitude $q, lattice termination ${z}_{0}, surface step height $\ensuremath{\xi}$, and band-gap index $m$.

J. Law,John Campbell +1 more
TL;DR: In this paper, a theoretical treatment of auto-ionization in β-decay is presented; a one-step model is assumed and explicit account is taken of the indistinguishability of the two continuum negatons.

W. Kreische,W. Lampert,G. Loos +2 more
TL;DR: In this article, the internal bremsstrahlung of 32 P and 90 Y was studied with various methods of measurement, including the measurement of the energy spectrum and the integral angular correlation of 32P and 90Y at angles Θ = 22.5°, 30°, 45° and 90°.

On the Surface States Associated with a Periodic Potential
TL;DR: In this article, the wave functions and energy levels associated with a finite one-dimensional periodic potential field are investigated and the surface levels appear only at lattice constants so small that the boundary curves for the allowed energy bands have crossed.

Band Structures of One-Dimensional Crystals with Square-Well Potentials
TL;DR: In this article, the energy band structure for a one-dimensional periodic square-well potential is obtained in terms of the well depth for the whole range of possible ratios of well width to hill width.
