Surface core-level shift of lead sulfide
Physical Review B, 1990The results of a photoemission study of the surface core-level shift of the Pb 5d level in the semiconductor PbS are reported. We found no surface shift within an experimental error of \ifmmode\pm\else\textpm\fi{}0.1 eV. Since this compound is highly ionic, this result is inconsistent with the theory that ionicity determines surface core-level shifts ...

Level Shifts in Predissociating Systems
Canadian Journal of Physics, 1975Analytical expressions are derived for the level shifts in systems undergoing type II predissociation. It is shown that the shifts at energies above the curve crossing point may be expected to oscillate in sign, with an amplitude comparable to the line width.

Perihelion shift and level ordering
Physics Letters A, 1984Abstract Properties of central potentials which determine a definite level ordering in quantum mechanics are shown to determine definite perihelion shifts of classical orbits. These properties are super- or subharmonicity of the potential off the origin, and convexity or concavity as a function of the radius squared.

DPOAE temporary level shift (TLS) at 2f(1)-f(2) and f(2)-f(1), ABR temporary threshold shift (TTS), and detailed histopathological findings were compared in three groups of chinchillas that were exposed for 24 h to an octave band of noise (OBN) centered at 4 kHz with a sound pressure level (SPL) of 80, 86 or 92 dB (n=3,4,6).

Radiative level shifts, I. Formulation and lowest order lamb shift
Annals of Physics, 1965Abstract In a series of papers, we shall develop and apply formal operator techniques for radiative level shift calculations. This first paper is concerned with the general formulation of the method and its application to the evaluation of the lowest order Lamb shift. An effort has been made to keep it pedagogically coherent, and a detailed review of

Shifting level modelling of hydrologic series
Advances in Water Resources, 1980Abstract The potential of applying shifting level (SL) models to hydrologic processes is discussed in light of observed statistical characteristics of hydrologic data. An SL model and an ARMA (1, 1) model are fitted to an actual hydrologic series. Computer simulation experiments with these models are carried out to compare maximum accumulated deficit
