The fusion of deuterium with tritium 3H+2H→4He+n+17.6MeV is even more efficient in that about four-thousandth of the total mass is converted into energy. The fusion fuel reserves in the form of deuterium, the heavy isotope of hydrogen with an isotopic abundance of 0.015%, are estimated to...

Here we report the upper limits on effective electron anti-neutrino mass, mν, from the second physics run of the Karlsruhe Tritium Neutrino experiment. In this experiment, mν is probed via a high-precision measurement of the tritium β-decay spectrum close to its endpoint. This method is ...
However, there is an important exception, namely the β decay of tritium, 3H, which turns out to be extremely sensitive to the absolute antineutrino mass. As is well known from the discovery of neutrino oscillations (see for example [588]), it can be shown that at least two from three ...
What is the binding energy per nucleon for the heaviest isotope of hydrogen, ^3H (called tritium)? The atomic mass of ^{35}_{17}Cl is 34.96885 u. What is its binding energy? How many atoms of hydrogen are in 220 g of hydrogen peroxide (H_2O_2) ?
Reznik [111, 112] found that satellite cells are more numerous in areas undergoing regeneration and that these cells incorporate tritium-labeled thymidine. He considered them "stem cells" capable of providing my- oblasts for the mature mammal and for regeneration of skeletal muscle tissue. lJi...
In the upper two panels of Fig. 1, we give |mee| as a function of the lightest neutrino mass mL for NO (in blue) and IO (in red). The optimistic limit of KamLAND-Zen, |mee|<36 meV at 90% C. L., has touched for the first time the IO prediction with a vanishing mL [71]...
