Systematic corrections in the extraction of the pi NN coupling from (p)over-bar-p->(n)over-bar-n differential cross sections

• We show that the pi NN coupling constant determined model-independently from Tip charge exchange is subject to a systematic shift, and, more significantly that the strong absorption in the critical region prevents a determination of the coupling constant
