摘要:
AbstractThis paper reports on expeeriments to determine the composition of thin aluminium + nickel films. The techniques used were similar to those described by both Rhodin and Weyl but for reasons of simplification of the calculations involved, the effective wavelength concept was employed. Fluorescence measurements were also made on aluminium + nickel powder compacts of known composition. The comparison of measured intensities from powder compacts and thin films revealed a strong particle size intensity dependence.

摘要:
AbstractTwenty‐five new measurements of Kβ/Kα X‐ray intensity ratios for elements in the atomic number range 20 to 30 confirm other recent evidence that the variation with atomic number in this region is much less than previously thought, but there is still some disagreement for atomic numbers above 27. A table of recommended values is

摘要:
AbstractIn X‐ray fluorescence, as well as other quantitative methods for determining trace metal concentrations, computer methods for extracting characteristic peaks from background are very important. Cases where background is large and nonlinear, or there are overlapping peaks, present difficulties in the development of simple computer programs which give an accurate analysis of the peak. The method of analysis that will be described here was developed to meet these demands. The basic concept is simple, and good accuracy and reproducibility are achieved in samples with large nonlinear background, as well as overlapping peaks. The analysis is essentially independent of backgroun

摘要:
AbstractThe pulsed beam technique has been used to achieved a high data acuumulation rate in an energy‐dispersive analytical system consisting of an electron probe analyser and the Harwell ‘Highspec’ pulse analyser system 3074. The use of fast beam switching ( ∼ 30 ns transient time) and the special timing facilities available in the Harwell equipment reduce the spectrum contamination due to displacement of the probe during switching to a low level and also provide precise measurements of live time, essential for accurate analysis. Analyses performed at spectrumaccumulationrate of up to 12 kP.P.S. shows agreement with accepted values to within ± 1% for major constituents. Simple modification of the system permits accumulation rates up to 2
