I. Bogdanovic et al., USE OF STIM IN THE PROTON MICROPROBE ANALYSIS OF SINGLE PARTICLES, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 85(1-4), 1994, pp. 732-735
Scanning proton microprobe data are usually presented as plots of elem
ental intensity maps. However, these maps do not present actual concen
tration distributions, due to variations in energy loss and X-ray abso
rption, caused by local changes of the sample areal density and topolo
gy. Scanning transmission ion microscopy (STIM) is the method that can
provide additional information of importance for evaluation of these
effects. The use of particle shape and areal density distribution, det
ermined by STIM, in the case of single particle analysis is presented
in this paper.
