WebApr 7, 2006 · From these masses a new Q -value of the tritium β-decay was derived resulting in 18.589 8 (12) keV, being the most accurate value at present. The Q -value of the tritium β-decay is related to the possible rest mass of the electron antineutrino. Export citation and abstract BibTeX RIS Previous article in issue Next article in issue References WebAug 31, 2007 · The tritium effect was greater in weldments (67 % reduction vs. 37% reduction) largely because the ductile discontinuous delta-ferrite interfaces were embrittled by tritium and decay helium. Fracture toughness values decreased for both base metals and weldments with increasing decay helium content in the range tested (50-200 appm).
