levels

Hello. 

Some of the files in G4NEUTRONHPDATA/Inelastic/Gammas contain levels that are not in ascending order. Attached levels.txt contains a list of "file:#line" where this inconsistency is found. There could be more of them. I printed out only the first finding for each file. 

Attached gammas.txt contains a list of 
"file:#line 'level_energy photon_energy intensity'" 
which has photon_energy > level_energy by a lot. Also, all these .000 look a bit suspicious. 

Some files has both of these abnormalities. 

Check out z32.a687. How did it even get there? 

It is clear that there is a bug somewhere along the code used for production this library.

It seems that the gamma files are older than the others.  Maybe they have not been processed recently, but I agree there is a problem with the code used to create G4NDL.
I will check with the maintainer of G4NDL.

Your corrected gamma files (without meta-stable states) will be included in the next version of G4NDL.   This will be available for download soon as G4NDL4.7.
