Abstract

The spectacular decay mode $F^{+} \to p \bar{n}$ would be easily observed if the annihilation mechanism actually dominates the standard one (light-quark spectator) in the disintegrations of charmed particles. Its branching ratio would be about $10^{- 2}$ . Otherwise, it should be very rare (≃ $10^{- 6}$ ) because of partial conservation of axial current.
