I'm trying to simulate scattering of neutrons off liquid neon using G4ELASTIC1.1. This has worked well with liquid argon. When I do liquid neon, however, a LElastic scattering event turns the recoil nucleus into a Na22 nucleus, instead of a Ne20. One example of the result is that the deposited energy shifts from that expected from a mass number of 20 to that expected for a mass number of 22.
Hi Walter, I tested the G4LElastic model and the G4HadronElasticProcess in isolation for neutrons on liquid neon. I tried incident neutron energies of 1, 10, 100 and 1000 MeV and looked for the recoils. I did not observe any Na22. I did these tests in Geant4 V 8.2, so perhaps you could repeat your simulation using this release. Is it possible that you had radioactive decay assigned to the recoil? That would explain the Na22. If, after trying your simulation with V8.2 and you still see Na22 showing up, please send me detailed information about your setup and I will try to isolate the problem.
