Abstract An approximate parameterization of an exact expression for the reflection coefficient η l , that describes elastic scattering by a spin-independent complex potential, yields a parameterized-phase-shift model of elastic scattering. The parameterization is based on a detailed study of the role played by the nuclear surface region; the ...

Physical Review Letters, 1959
A construction is given of an equivalent one-body pocomplex target. The case of incident and target particles being identical nonrelativistic fermions, and allowing fully for antisymmetry, is considered explicitly. (A.C.)

The theory and modeling of optical MEMS structures are discussed in this chapter. Optics is also related to the processing of silicon MEMS in many ways, but here the focus is on the optical MEMS structures themselves and not on their fabrication methods.

Adaptive optics performance model for optical interferometry
Applied Optics, 2007The optical interferometry community has discussed the possibility of using adaptive optics (AO) on apertures much larger than the atmospheric coherence length in order to increase the sensitivity of an interferometer, although few quantitative models have been investigated.

A volume density optical model
Proceedings of the 1992 workshop on Volume visualization - VVS '92, 1992A simple, but accurate, formal volume density optical model is developed for volume rendering scattered data or scalar fields from the finite element method, as opposed to scanned data sets where material classification is involved. The model is suitable either for ray tracing or projection methods and allows maximum flexibility in setting color and ...

A Model for the Optical Transistor and Optical Switching
Journal of Modern Optics, 1991Abstract We propose a model for the optical transistor which can also be used for optical switching. We consider the ‘resonant optical tunnel effect’ and we show that the amplification of a modulation may be obtained by acting on the index of refraction of the intermediate nonlinear layer of a multilayer optical film.

Approximate optical system model
Applied Optics, 1976An analytical development is presented for on-axis far-field irradiance in terms of an optical system that specifies a laser beam quality, an optical train with both linear and nonlinear phase aberrations (power driven), and a focusing telescope with jitter.

Abstract In Chapter I we introduced the optical potential in order to account for the loss of current in the elastic channel owing to the coupling to non-elastic channels. The treatment there was purely phenomenological. It was based on an analogy with optics, where a complex index of refraction fulfils the function of a scattering ...

Aside from its intrinsic interest, the optical model of the scattering of neutrons from nuclei has a number of practical uses. It allows one to correlate large amounts of data on elastic scattering, absorption and total cross sections and hence to predict by extrapolation the cross sections for targets or energies as yet unmeasured.
