Hello,
With the version 11.01 of geant4 for some reason i obtain a Lifetime of 0s for some isotopes but not all of them. If I am printing the G4IonTable
of Ta178
for example :
G4IonTable* IonTable = G4IonTable::GetIonTable();
int Z = 73;
for (int A = 178; A <= 178; ++A) {
G4Ions* Ion = dynamic_cast<G4Ions*>(IonTable->GetIon(Z, A, 0));
if (Ion == 0) continue;
Ion->DumpTable();
I obtain this :
--- G4ParticleDefinition ---
Particle Name : Ta178
PDG particle code : 1000731780 [PDG anti-particle code: 0]
Mass [GeV/c2] : 165.718 Width : 0
Lifetime [nsec] : 0
Charge [e]: 73
Spin : 0/2
Parity : 1
Charge conjugation : 0
Isospin : (I,Iz): (0/2 , 0/2 )
GParity : 0
Quark contents (d,u,s,c,b,t) : 251, 283, 0, 0, 0, 0
AntiQuark contents : 0, 0, 0, 0, 0, 0
Lepton number : 0 Baryon number : 178
Particle type : nucleus [generic]
Atomic Number : 73 Atomic Mass : 178
**Stable : unstable -- lifetime = 0 ps**
Decay table should be consulted to G4RadioactiveDecayProcess.
The same output with a precedent geant4 version (10.2) where i get the right lifetime :
--- G4ParticleDefinition ---
Particle Name : Ta178[0.000]
PDG particle code : 1000731781 [PDG anti-particle code: 0]

Lifetime [nsec] : 1.22571e+13
Charge [e]: 73

AntiQuark contents : 0, 0, 0, 0, 0, 0

Particle type : nucleus [generic]
Atomic Number : 73 Atomic Mass : 178
**Stable : unstable -- lifetime = 12257.1 s**

In my physics list i am using G4RadioactiveDecayPhysics
and G4RadioactiveDecay
.
