Abstract
We investigate radiative pion capture in hydrogen, π- → nγ, as a means of determining the parity-violating πNN coupling constant f{hook}π. We include contributions from the lightest baryon resonance [Δ(1232)] and the light vector mesons [ρ, ω, φ]. Our results indicate that, despite their negligible role in parity-conserving amplitudes, the effects of the Δ and ρ may hamper the determination of f{hook}π. © 1981.
