Created attachment 485 [details]
output of Hadr03

In attachment, a result of ParticleHP + G4TENDL1.3 : proton (10 MeV) on O16

1- I would like to know what means the warning " More than one neutron ...." and how serious it is.
2- There are many channels open. Are, all of them, real and exact  (in particular their balance Q) ?
     For comparison, the end of output is results with Binary cascade.

Hi Michel,

   Consulting with Tatsumi, the answers to your questions are:

1) "More than one neutron... " means that the final state was adjusted to add one or   more neutrons in order to get exact energy balance or correct baryon number, or similar things.  The warning is just for your information and does not mean anything is wrong.

2) The answer to the second question is also an explanation of why the final state modification is done.  In ENDF, many final state channels are not listed exactly.  In the case of multiplicity, for example, sometimes only average values are known.  So the mean multiplicity from measurement may be listed as 3, but the actual multiplicity is 4.  In that case the final state modification is made and a warning is printed that this was done.
