I've added your suggestion to the .in file as directed, but the following error message occurs (see bottom of this message):

G4RadioactiveDecay::DoIt : can not determine decay channel

Segmentation fault: 11

I am attaching the changes to the .in file, and the modified fullChain.mac.

Am I missing something here?

Thanks for your help Jim
