摘要

Using a data sample of 1.06 x 10(8) psi' events collected with the BESIII detector in 2009, the branching fractions of chi(cJ) -> p (n) over bar pi(-) and chi(cJ) -> p (n) over bar 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) -> p (n) over bar pi(-) and chi(c2) -> p (n) over bar pi(-) are consistent with, but much more precise than, those of previous measurements. The decays of chi(c1) -> p (n) over bar pi(-) and chi(cJ) -> p (n) over bar pi(-)pi(0) are observed for the first time.
