A vertical experimental set-up for simultaneous recording transmission and scattering Mössbauer
spectra is described. Application of the apparatus for the study of model powder mixture of two
components with different grain sizes shows differences in the relative intensity ratio of these
fractions in absorption and conversion electron Mössbauer spectroscopy (CEMS) spectra. This effect,
explained as a result of the size selectivity of CEMS technique, is parameterized by the grain
radius ratio of components. The possible application for investigation of isolated surface nano-
and microobjects is discussed.
