In Gate project, we used rayleight data available in G4EMLOW/rayl with G4EMLOW version 7.13.
But with Geant4 version 11, I had G4EMLOW version 8.0 and the previous folder does not exist anymore.
I found there is also in version 7.13 a folder called G4EMLOW/livermore/rayl. But if I do the difference of that folders, they are not exactly the same.
Could you explain us the difference please ?
