Question Physics List for Charge state and momentum distrbution after grazing the target 

Forum: Physics List
Date: 25 Oct, 2012
From: Zhengzheng Liu <Zhengzheng Liu>

I am trying to simulate the charge state and momentum distribution after the target.I use "QGSP_BERT" physics list but the output looks incorrect:

Projectile beam Uranium 17 MeV/u with charge state 33+; Target Material Carbon 3 micro-meter; Charge state is obtained through sensitiveDetector class by:

G4double pcharge = prePoint->GetCharge();

I should get 80% of the charge states from 76+ to 80+ according to LISE++ program. But with Geant4, I only get a single charge state 63+.

Could anyone help me with that? I appreciate it a lot.
