32 // File name: G4PAIModelData
33 //
34 // Author: V. Ivanchenko based on V.Grichine code of G4PAIModel
35 //
36 // Creation date: 16.08.2013
37 //
38 // Modifications:
39 //
40 // 04.10.13 V. Grichine add cut of dE/dx, redirect <dE/dx> to std::vector<G4PhysicsLogVector*> fdEdxTable;
41 //
42 //
43 // Class Description:
44 //
45 // Implementation of PAI model internal data class.
46 // This class is extracted from G4PAIModel in order to provide sharing
47 // of these data between threads.
48 //
49 // Internal data tables are computed for proton.
