## Description

- description: Electron probe micro analyzer is used for the composition analysis
    of a wide variety of materials, and its quantification is almost established as
    a ZAF method. The quantification of MgGe alloy, however, showed an anomalously-high
    total concentration (ie.120%) of the elements of Mg and Ge. The present analysis
    of MgGe alloy was not considered to be correct according to the additional fact
    that the estimating concentration of Mg increase as the increase of accelerating
    voltage of the electron beam. Because the mass absorption coefficient of Ge for
    MgKa, is an essential parameter of the ZAF method, we then determined the mass
    absorption coefficient of Ge for MgKa by using measured X-ray peak intensity ratios
    of Ge and Mg of MgGe alloy to the standard materials (MgO and Ge). The resulting
    mass absorption coefficient of Ge for MgKa was 5561±200 cm2/g which were obtained
    between the electron-beam accelerating voltage of 15kV ～and 30kV. It is smaller
    than the previous mass absorption coefficient of 7510 cm2/g, which lead the anomalous
    quantification error. The difference of the mass absorption coefficients must
    be caused by the difficulty of the measurement of the mass absorption coefficient
    of Ge for MgKa energy of which is close to the Ge LⅠand LⅡabsorption edges.
