|
// Description: This class (a proxy of the class G4NuDEX) uses
|
|
// the NuDEX model to produce gammas and internal
|
|
// conversion electrons from neutron capture.
|
|
// Whenever NuDEX is not applicable, G4PhotonEvaporation
|
|
// is used.
|
|
// The implementation of this class follows the code
|
|
// of the class G4NeutronRadCapture.

|

// Modifications:

|
// Class to use NuDEX model inside Geant4
