output of Hadr03

Geant4 10.5-beta
Thermal neutron capture on Ag109. BinaryCascade model.

From the output of Hadr03 (attached), we can compute :
 - cross section of n + Ag109 -> Ag110 ground state : 82.4 * 0.035 =  2.9 barns
 - cross section of n + Ag109 -> Ag110[117.59 keV]  : 82.4 * 0.964 = 79.4 barns

These values are not compatible with values given in literature.
I attach the plots provided by Sergio Lo Meo; see hyper news hadronic processes #1657

Sorry for not re-assigning this before now; I thought it was a ParticleHP bug, but according to hadronic HyperNews #1657 it appears to be a G4NeutronRadCapture problem.

Hi Michel,

can you, please, check this with 10.6?

I have not yet upgraded to latest version (will do in January)
With 10.6-cand-01, results are basically unchanged.
