The xray_TESdetector example in Geant4 example library (src/examples/advanced/xray_TESdetector) uses its own physicslist called ‘Space Physics List (SPL)’ with XrayTESdetPhysicsList.cc and G4EmStandardPhysics_SpacePhysics.cc.

In the constructor of XrayTESdetPhysicsList, the RadioactiveDecayPhysics is reistered in the following way:

XrayTESdetPhysicsList::XrayTESdetPhysicsList() : fMessenger(nullptr), fEmPhysicsList(nullptr), fParticleList(nullptr)
{
  fMessenger = new XrayTESdetPhysicsListMessenger(this);
  G4LossTableManager::Instance();
  verboseLevel = 1;

  // Particles
  G4cout << "1 - Defining DecayPhysics" << G4endl;
  fParticleList = new G4DecayPhysics("decays");

  // Radioactive decay
  G4cout << "2 - Defining RadioactiveDecayPhysics" << G4endl;
  RegisterPhysics(new G4RadioactiveDecayPhysics());
  
  // EM physics
  G4cout << "3 - Defining Standard em" << G4endl;
  fEmName = G4String("local");
  //fEmPhysicsList = new PhysListEmStandard(fEmName);
  fEmPhysicsList = new G4EmStandardPhysics();
}

However, if we run xray_TESdetector with run01.mac, which includes the /process/list command, the log shows Decay in registered process, but does not show Radioactivation in registered process.

So why does radioactive decay physics not registered with the RegisterPhysics(new G4RadioactiveDecayPhysics()); command?
