Feel free to use the plots linked below for converting the
measured PALS lifetime into mean pore dimension. Calculations for square
channels and cubic pores (presented on each plot) are done for several
temperatures. For more information on the calculations, please see

Determination of Pore Size in Mesoporous Thin Films
from the Annihilation Lifetime of Positronium,
The Journal of Physical Chemistry B 105, 20, 4657 (2001).
Please note, that in these plots the delta
dimension has been subtracted from the pore well radius as is traditionally done
(but was not done in the above paper). Please use the above paper as a reference
if you use these curves for a publication.
