Abstract: (arXiv)

Using a data sample of

1.06 \times 10^{8}

\psip events collected with the BESIII detector in 2009, the branching fractions of

\chi_{cJ}\to p\bar{n}\pi^{-}

and

\chi_{cJ}\to p\bar{n}\pi^{-}\pi^{0}

(

J

=0,1,2) are measured{Throughout the text, inclusion of charge conjugate modes is implied if not stated otherwise.}. The results for

\chi_{c0}\to p\bar{n}\pi^{-}

and

\chi_{c2}\to p\bar{n}\pi^{-}

are consistent with, but much more precise than those of previous measurements. The decays of

\chi_{c1}\to p\bar{n}\pi^{-}

and

\chi_{cJ}\to p\bar{n}\pi^{-}\pi^{0}

are observed for the first time.
