Hydrogen Isotopes Exchange Reactions
in UT-Austin / MTU Neutrino
Experiment
The Texas/Michigan neutrino experiment aims at determination of neutrinos
mass via observation of electron energies in tritium beta decay. One of the
major concerns in this experiment is purity of tritium and identification
of
other hydrogen isotopes. Work with multiple hydrogen isotopes at the same
time is often accompanied by isotopic mixing. Formation of HD and TH,
molecules as a result of interaction between the materials surface in
gaseous hydrogen isotopes mixtures of H2, D2 and T2 have been the subject
of
many studies. The partial pressures of the species are usually monitored
with a mass spectrometer. However, mass spectrometry and gas chromatography
differentiate poorly between HT and D2. Laser Raman spectrometry offers
excellent differentiation among hydrogen isotopomers containing tritium and
deuterium but offers only modest sensitivity. I will describe the use of
simple Raman system which monitors traces of HD in H2 and D2 mixtures at
levels of parts per million in minutes time of observation.
