Abstract
From a refined non-relativistic quark model that fits the baryonic low -energy spectrum the study of strong pion decay processes within an el ementary emission model scheme points out the need of incorporating si ze-contributing components into the baryon wave functions. In particul ar the effect of a (qqq <q(q)over bar>) component is investigated in t he framework of a quark pair creation model.
