Chemical states of tritium in solid lithium compounds irradiated with neutrons
TLDR
In this article, the chemical states of tritium existing in neutron-irradiated solid lithium compounds were analyzed using a radiometric method, and it was found that nearly 100% of trite was found in the T+ state in LiOH, Li2O2 and Li3N, while the T− state predominated in LiH, Li7Pb2, and Li2C2.Abstract:
Chemical states of tritium existing in neutron-irradiated solid lithium compounds were analyzed using a radiometric method. Nearly 100% of tritium was found in the T+ state in LiOH, Li2O2 and Li3N, while the T− state predominated in LiH, Li7Pb2 and Li2C2. Tritium incorporated in Li2O, Li2S, LiF, LiCl, LiBr and LiI was distributed over the T+, T− and T0 states. In Li2O crystals, the distribution of tritium in the T+ state increased from 58% to 81% with increasing neutron fluence from 2.5×1016 cm−2 to 6.3×1017 cm−2.read more
