Re: stopping power tabulations

Hi Bob,

without looking at your input file I can only guess that you have not
followed correctly the instructions in the manual.
I would like to remind you and all users to ALWAYS send the input file
and possible user routines when inquiring about an error.

Anyway, the instructions on the manual say that you have to use
DELTARAY with SDUM=PRINT. Did you do that?
If you did it, you should find the tabulations of dp/dx (not dE/dx!)
printed in the xxx.out file.

Stopping power refers only to electrons and charged particles. There is
no such quantity for photons.
