None G4RadioactiveDecay Exception 

Forum: Particles
Date: 08 May, 2014
From: Nick Patterson <Nick Patterson>

I have simulation whereby I define a particle using:-

     G4ParticleDefinition* ion = G4IonTable::GetIonTable()->FindIon(71,177,0);

I get the following error when running Geant.

-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : HAD_RDM_011
      issued by : G4RadioactiveDecay::GetMeanFreePath()
Ion has negative lifetime -1001 but is not stable.  Setting mean free path to DBL_MAX

*** This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------

I have never seen this before and wondered if anyone knows under what circumstances this problem arises?

Regards, Nick.
