    "abstract": "We utilize precise weak interaction experiments on atomic muon capture and\nbeta decay in the A = 3 nuclei, and take into account the effects of nuclear\n\"anomalous thresholds\" to extract the pseudoscalar pi-^3He-^3H coupling\nparameter, G^{eff}(m_\\pi^2) = 45.8+- 2.4. This is an order of magnitude\nimprovement in precision over that from the use of pion-nuclear scattering data\nand dispersion relations.",
