Abstract:
A single-step, self-contained method for
determining the crystallite-size distribution
and shape from experimental x-ray line
profile data is presented. It is shown that
the crystallite-size distribution can be
determined without invoking a functional
form for the size distribution, determining
instead the size distribution with the
least assumptions by applying the
Bayesian/MaxEnt method. The
Bayesian/MaxEnt method is tested using
both simulated and experimental CeO2
data, the results comparing favourably
with experimental CeO2 data from TEM
measurements.
