Abstract

The extrapolated end-point of the tritium beta spectrum has been measured in a tritium-implanted Si(Li) detector for which the radiation damage has been kept small. The result is 18577±7 eV. Adding the maximum recoil energy, the ${}^{3}-^{3}$ He atomic mass difference is taken to be 18580±7 eV.
