Large radial component

The large radial component is expanded in a set of Gaussian-type functions (GTE) [Ishikawa et al. (1991)]... 

It is also necessary to choose the position number and size of sensors to sample the magnetic field with accuracy. As the radial component of this field is null in the median plan of the excitation coil when no flaw is present, it seems obvious to measure this component, so we can use large gain amplifiers, figure 1 shows the typical aspect of the magnetic field for a ponctual flaw when a very long excitation coil is used ... 

It is known that SAR observations of a moving target (ship) allow us to calculate the target s velocity. In a case under study, the radial component of the ship s velocity accounted for 0.4VS and the eastward shift of the ship relative to its wake (spill) caused by this component was estimated with a large error, that hindered the accurate determination of ship velocity. Thus, assume that Vs = 25 km h"1. 

Two kinds of counterions, condensed and those constituting a diffuse ion atmosphere that may be treated in the Debye-Htickel approximation, are clearly recognized in their distinct spatial distributions, and introduction of the partial polarizability tensor enables us to distinguish between contributions to the polarizability from these two kinds of ions. The contribution from condensed counterions to the radial components of the polarizability tensor is very small, as has hitherto often been postulated in various theories. That from the diffuse ion atmosphere is very large and cannot be neglected in the calculation of the anisotropy. 

Here and /i., are the upper and lower radial components of the ground state Dirac wavefunction, defined self-consistently, and r> = max(r,/) This function can be shown to have the asymptotic value of 2, which leads to the physically sensible picture of an electron at large distances from the nucleus in a lithiumlike ion seeing the nuclear charge screened to Z — 2 by the ground state electrons. 

Here, the summation extends over both negative and positive energy spinors. Pnn > ) and Qr if) are the large and small radial components and are expanded in G spinors, x il and xfi, that satisfy the boundary conditions associated with the finite nucleus [Ishikawa et al. (1997b)),... 

Here, P and Q are the radial large and small components of the wave function. The factor of i has been introduced to make the radial components real. The angular functions are two-component spinors, that is, a product of angular and spin functions the spin variable r has been explicitly shown.
