G4SDParticleFilter: Particle <Li7> not found

Particles, Track, Event, Run and Biasing

Hi Geant4 experts,

I am converting my application from G4.9.6 to G4.10.06.
I am using command-based scoring to score the dose from several particles in a thermal neutron transport application. However, the core dumps when I add Li7 particle filter (screenshot attached).
I am not sure why Li7 is missing in the library. I checked through /particle/list command and Li7 did not exist.
Can you advise how I can add this particle? I didn’t have this issue in the old version.
Cheers, Leyla

Hi, this issue was resolved by adding Li7 manually in my macro file:
#########################
#Add new ions to the library
/gps/particle ion
/gps/ion 3 7
#########################

Define the primary beam

/gps/particle neutron
/gps/pos/type Point
…
I have been using GPS for primary generator. I presume that should work the same with G4Gun as well. Just that to be sure to add the new particle before primary beam or the new particle would be taken as the primary!

Cheers, Leyla
