Production of 203Os via fragmentation and ∆-excitations

Hello,

I am new to GEANT4, and I want to estimate production cross-section of 203Os(N = 127) via projectile fragmentation of 208Pb (N = 126) on 9Be target followed by ∆-excitations. It is possible to do? If yes, what are the Physics Process for this?

Here is simplified expression of one channel for above process:
208Pb(1000 MeV/u) + 9Be → projectile fragmentation → 203Ir → ∆-excitations → 203Os

Thank you in advance.
