At bulk density, a value typical in this experiment for the mass absorption coefficient 1000 [cm.
The uncertainty in the quantitative data also results from the choice of the mass absorption coefficients to be used for the calculation of the f([chi]) absorption correction factor.
He has published more than 100 archival papers concerned with developments of EPMA instrumentation, improvements in microanalysis techniques, metallurgical and geological applications (including lunar samples and asbestos), characterization of microanalysis standards, uncertainties in quantitative EPMA and correction procedures, bibliographies of EPMA publications, tables of mass absorption coefficients and x-ray lines, development of matrix correction procedures, the early use of color in wavelength dispersive x-ray dot mapping, energy dispe rsive qualitative and quantitative analysis, and the use of Monte Carlo techniques in quantitative EPMA.
