Question optical photon self-absorption in scintillator

Hello!

I am running geant 4.7.0.p01 and doing some optical photon simulations.

My question is this:

I would like to simulate optical photon absorption and RE-emission in a plastic scintillator. I am using wavelength dependent values for all the physics. To my knowledge, this reqires setting

scintMPT->AddProperty("ABSLENGTH",scintEnergy,scintAbsorb,scintEntries); scintMPT->AddProperty("FASTCOMPONENT",scintEnergy,scintEmit,scintEntries); scintMPT->AddProperty("SLOWCOMPONENT",scintEnergy,scintSlow,scintEntries); scintMPT->AddProperty("WLSCOMPONENT",wlsEnergy,wlsEmit,wlsEntries); scintMPT->AddProperty("WLSABSLENGTH",wlsEnergy,wlsAbsorb,wlsEntries);

for the SCINTILLATOR (along with the other properties). I am not using WLS fibers, but I am using WLS properties in the scintillator to get the primary emission, wls absorption, wls emission and non-wls absorption.

I am running into problems with:

G4SteppingManager::InvokePSDIP(unsigned long) G4SteppingManager::InvokePostStepDoItProcs() G4SteppingManager::Stepping() G4TrackingManager::ProcessOneTrack(G4Track*) G4EventManager::DoProcessing(G4Event*) G4EventManager::ProcessOneEvent(G4Event*)

Doing a bt I find that the error is in G4MaterialPropertyVector::GetProperty()

I can't find the problem. Is what I am doing even possible in G4?

Thanks!!
