Hi, Tom

 We do not plan to implement rare decay modes.  
 Please add the decay mode in your application.

 As for the pi+ -> e+ + nu_e decay, insert following lines in your physics list.
 (Or anywhere after registration of physics list) 

  G4ParticleDefinition*  pPi = G4PionPlus::PionPlusDefinition();
  G4DecayTable* table = pPi->GetDecayTable();

  // select pi -> mu + nu  and set BR = 1 - 1.23e-4
  G4VDecayChannel * cMuNu = table->GetDecayChannel(0);

  // create pi -> e + nu channel and register it
  G4VDecayChannel* mode = new 
 (Do not forget include "G4DecayTable.hh" and "G4PhaseSpaceDecayChannel.hh")
