I’m trying to model activation process of indium plate in neutron field, and get strange results. Using version 10.5.p01 and extended example “Activation”, in wich i modified geometry a bit, i can’t obtain any nuclei of In116[127.267] - the first metastable isomer of indium with T1/2 about 54 minutes.
I have tryed to look at different neutron energies from thermal to 14 MeV, but still no success.
Then i changed the gun particle from neutron to deuteron, and with high deuteron energy i finally observe this metastable indium isotope, but this is not what i’m looking for.
In literature there is a lot of proof that this is not rare reaction, and In116[127.267] should produce at almost same rate as In116 in ground state with T1/2 about 14 seconds, but i can’t get this result in model.
Has anyone come across with similar problem? And if so, please, tell me what to do.
Thanks in advance.
