I have tried to calculate partial fragmentation cross sections for 28Si + Pb using G4BinaryLightIonReaction, G4WilsonAbrasion and G4QMDReaction models. In the simulation work, no models exactly shows the odd-even effect as shown by experimental data. But BIC and QMD models well show the suppression for the fragment with the charge Z = 9. I have seen similar behavior in other interactions also. I need the explanation why they are not able to able the exactly odd-even effect and why they have show the suppression as shown by experimental data?
Also in the presentation of A.Ivantchenko (Validation of Geant4 models with Ion/Ion interactions, page 18-21), similar type of behavior has been observed.
Can anyone give me explanation regarding this?
