Hi,

I'm working on rdecay02 example (geant4.9.6.p01). I tested rdecay02.in
using /exrdm/phys/SelectPhysics QGSP_BIC_HP, and it works. However, I
used the Hadron option (/exrdm/phys/SelectPhysics Hadron), and I got the
following error:

-------- EEEE ------- G4Exception-START -------- EEEE -------

It says "Cross section is not available"......any idea ?

Thanks,

Mohammad

This is now fixed with the addition of an elastic model and cross section to the elastic scattering process for generic ions.  You will need to use Geant4 version 10 with a future patch containing this fix.
