Abstract
We present an analysis of the processes and (ground state) on the basis of an "elementary particle" treatment and of a "microscopic" treatment including the nucleons-only impulse approximation and the meson exchange. The elementary particle treatment in conjunction with data on (2.31 MeV), conserved vector current, partially conserved axialvector current, and a possible second-class axial current, yields and . The microscopic treatment leads to the conclusion that the nucleons-only-impulse-approximation and meson-exchange contributions to the amplitude may well be opposite in sign and comparable in magnitude so that the destructive interference between them contributes significantly to the anomalously small values of and .
