Abstract
Pion decay widths of nonstrange-baryon resonances are calculated based on the /sup 3/P/sub 0/ quark-pair-creation model. The decay mechanism is consistent with the description of the nucleon and of the pion as having quark structure related to a flux-tube model motivated by QCD. The spectroscopic model has no adjustable parameter. The /sup 3/P/sub 0/ model has one parameter which we fit to reproduce the ..delta..(1232) decay width. The results for 19 resonances are compared to experiment and to results obtained from the pseudoscalar-emission model. This sheds some light on the role of the finite size of the pion.
