From Figure 14 it is evident that the values of [absolute value of ([Z.sub.6])] for all the boundary stiffnesses increase to attain maximum value and then decrease up to grazing incidence. The values for NS1 and TS1 are greater than the values for NS2 and TS2, respectively, that reveals the thermal relaxation time effect.

Therefore as measuring technique of choice for such a task grazing incidence small-angle X-ray scattering (GISAXS) was selected.
To investigate the molecular packing and inner film morphology of the deposited films, X-ray scattering measurements in grazing incidence geometry were performed.
where [absolute value of *] denotes the magnitude of the argument, and the two reflection coefficients corresponding to the perpendicular and parallel polarizations under the grazing incidence can be expressed as [11]
UCSD has demonstrated a grazing incidence final optic mirror with high damage threshold.
GIXS (grazing incidence x-ray scattering), EXAFS (extended x-ray absorption fine structure), and SXS (surface x-ray scattering) are useful in electrochemical studies chiefly because "you see a larger area than in STM," says Michael Toney of IBM's Almaden Research Center, San Jose.
