Abstract
The residues of the nucleon and Δ baryon poles in the baryonic current propagator are evaluated for the MIT and chiral bag models. It is found that the values obtained with a bag radius of 0.8 to 1 fm match those predicted by the quantum chromodynamic sum rules which take into account the chiral structure of the physical vacuum state. Smaller bag radii give increasingly poorer agreement.
