Abstract

Various determinations in the current literature of the π3He3H coupling constant are reexamined, and the ones leading to very low values are shown either to be erroneous or not decisive and implausible. A dispersion relation and the impulse approximation which use the same kind of approximations both lead to Gπ−3He−3H(−m2π) ≈ −1.7, in absolute value higher than the elementary nucleon value gπpn(−m2π)=1.41.
