I want to use SRIM stopping powers for simulation of Li ions.
I have found out that ICRU model provided stopping powers differ by a significant amount when compared to SRIM values. Is there any way to incorporate SRIM stopping powers in my calculations?
I have seen, that SRIM parametrisations were included in G4hLowEnergyIonisation class, however, in the 10.7 version of GEANT4 such class is gone. I tried using G4AtimaEnergyLossModel class, which should use SRIM parametrisation for energies below 10 MeV/u, however, in the region of interest (2.7 MeV Li ions), the stopping power is about ~13 eV/A lower than SRIM values. On the other hand, when using G4IonParametrisedLossModel, which uses ICRU data, the stopping power is by ~13 eV/A higher than SRIM values. Is there a simple way to include SRIM stopping powers in my simulations? The considered energies are in the range of 3 MeV to 100 keV.
I was thinking of using a modified G4IonParametrisedLossModel class to add different dedx table in function AddDEDXTable(…), but G4IonStoppingData class uses G4LEDATA path, so this class would need to be modified also.
Hope I described my problem clearly.
