Problem 449

If I read the manuals correctly, the "normal" photoelectric process does not
include fluorescence of the excited atom after the photoelectron is ejected.
The low energy photoelectric effect does include fluorescence, but does not have
a realistic distribution of photoelectron theta angles (the electron is simply
emitted in the direction of the incident photon).  Is this correct?  How can I
get both processes?  I'm simulating gas detectors, and both the photoelectron
and fluorescence photon have large ranges and need to be tracked.

By the way, according to my old GEANT3 manual, GEANT3 did include both of these
processes in its photoelectric effect.  At least I know it did have
fluorescence, since I got realistic escape peaks in my detector response back
when I was using GEANT3 (years ago...)  Thanks for your help...
