Abstract

By accounting for rapidly varying pole terms, the current-algebra-PCAC (partial conservation of axial-vector current) procedure properly measures large decay momentum corrections in charmed

D^{+} \to {\bar{K}}^{0} π^{+}

D^{+} \to {\bar{K}}^{0} K^{+}

, and

Λ_{c}^{+} \to p {\bar{K}}^{0}

weak decays.
