One such approach to counter the effects of spherical aberration is to record a through-focus series, which allows reconstruction of the electron exit-wave function and thereby removal of the spherical aberration. The basic idea of this reconstruction approach, as implemented in the Truelmage software package, will be described after a simplified introduction to HRTEM imaging theory (for more details see Williams and Carter 1996, Reimer 1984, Spence 1988). Furthermore, two application examples are shown to discuss the benefits of focal-series reconstruction and illustrate the information that can be obtained. [Pg.374]

In linear imaging theory, it is assumed that the object is a weak scatterer, so that the quadratic term in equation 5 is small and can be neglected... [Pg.376]

Galashin and associates (152,228-231) approach latent image theory on the basis of thermodynamical reasoning and the belief that chemical sensitization is primarily of the reduction type. [Pg.380]

Compton and Langmuir consider that the law of force F(x) between the electron and the surface is of the form shown in Fig. 49 the dotted line shows the course of a law of force on the image theory alone. At a certain distance from the surface the attraction on the electron becomes less than that required by the simple image force, reaches a maximum, and then gradually falls to zero as the interior of the metal is approached. [Pg.311]

Let us now examine the extent to which these predictions are supported by experiment. Unfortunately, both practical and theoretical difficulties attend attempts to investigate the detailed shapes of particles in the range 0.6-0.9 nm that would include the 7- and 13-atom clusters mentioned above. Extremely high resolution would be required and problems exist in the application of imaging theory to such small supported particles. So the approach for the present must be to investigate the shapes of somewhat larger particles (> 2 nm) and from this information to adduce the morphology of smaller clusters. [Pg.78]

An important class of hetero-interface is that between metals and ceramics. This occurs in such areas as metal oxidation and catalyst support. It is also important in understanding such phenomena as wetting. Stoneham and Tasker (1985) argued for the importance of image terms in the adhesion of these interfaces. Simple image theory predicts that the adhesion energy of a... [Pg.194]

In general, the study of the scattered intensity by systems where multiple scattering is non-negligible is a difficult task. In order to resolve these difficulties we have used several approximations the particle size is assumed to be much smaller than the incident wavelength, so the Rayleigh dipole approximation is used to characterize the particle scattering. For the surface case, the perfect conductor approximation (PCA) ( = -go) for the substrate is applied. In both systems, the scattered field is calculated in the far-field approximation. For the purpose of this research, these approximations do not constitute serious restrictions and facilitate the numerical calculations. For real substrates (metallic or dielectric) and/or finite size particles, the main conclusions are unaffected [9]. The scattered intensity is calculated by means of the coupled dipole method (CDM) [10] for both the volume case and the surface case. In the latter, the PCA allows us to apply the image theory [11]. [Pg.179]

In this chapter we present the backscatter polarization signals resulting from small particles located in the proximity of a planar interface. This system was treated by Lindell et al. [22] and Muinonen et al. [23] using Exact Image Theory (EIT). Simnltaneously, and in the same journal issue, Videen [24, 25]... [Pg.210]

The theory of contingent decision making (Beach and Mitchell 1978 Payne et al. 1993) is similar to image theory and cognitive continuum theory (see Section 4.1.4) in that it holds that people use different decision strategies, depending upon the characteristics of the task and the decision context. Payne et al. limit their modeling approach to tasks that require choices to be made (simple memory tasks are excluded from consideration). They also add the assumption that people make choices about how to make choices. ... [Pg.2207]
