Question How can I define the radioactive decay of Tc-99m to Tc-99?

Hello everyone!

I am trying to simulate the radioactive decay of the metastable isotope Tc-99m and I use the following code.

 G4int Z = 43, A = 99;
 G4double ionCharge   = 0.*eplus;
 G4double excitEnergy = 142.6833*keV;

 G4ParticleDefinition* ion
 = G4ParticleTable::GetParticleTable()->GetIon(Z,A,excitEnergy);

Moreover, I read the answer of a relevant question in the forum, and I used also the command

 /grdm/nucleusLimits 100 100 43 43

as the answer suggested. However, in my simulation I see plenty of electrons, and only about 4-5% of gammas instead to observe the pure decay of Tc-99m to Tc-99. So, I suppose the simulation reflects the decay of Tc-99m to Tc-99 and Ru-99 and no only the decay to Tc-99. Does anyone knows how can I fix the problem and simulate only the decay of Tc-99m to Tc-99? I will appreciate any help :)

Best Regards. Georgios
