i have found that de/dx data for 48Ti penetrated Au is kind of incorrect with forward code:

G4EmCalculator calc;
    G4NistManager* man = G4NistManager::Instance();
    G4Material* material = man->FindOrBuildMaterial("G4_Au");
    G4ParticleDefinition* recoildefinition;
    G4IonTable* ito = G4ParticleTable::GetParticleTable()->GetIonTable();
    int Z = 22;
    int A = 48;
    recoildefinition = ito->GetIon(Z, A);

    size_t N = 20;
    double lowE = 1./100*48;
    double highE = 1.*48;
    std::ofstream file;
    file.open("48TiAu.csv", std::ios_base::app);
    for(unsigned i = 0; i <= N; ++i){
        double KinE = log(lowE) + i*(log(48) - log(48./100))/N;
        auto dEdX = calc.GetDEDX(exp(KinE), recoildefinition, material);
        file << exp(KinE)/A << " " << dEdX << std::endl;
    }
    file.close();
    exit(0);

For example i did several tests with 48Ti on Ag, Al, C, Ge, Ti and they was fine. The full obtained data attached
