Question Pa234[73.920] vs Pa234[73.920X]

Hi,

how can I get a G4ParticleDefinition pointer from G4IonTable to Pa234[73.920X] as opposed to Pa234[73.920]? Pa234[73.920X] is Pa234m, right? I tried IonTable::GetIon using the Pa234[73.920X] encoding (1000912341), but it returns a NULL pointer. I am including the Dump info from both particles below. I am using Geant4 10.03. Thanks!
