It is a pleasure to acknowledge many helpful discussions with Dr. G. A. Miller and Mr. S. Theberge. One of the authors (L.R.D.) wishes to acknowledge the hospitality of the TRIUMF theoretical group. We would also )ike to thank the following organizations for their financial support: National Sciences and Engineering Research Council (A.W.T.), Junta de Energia Nuclear, Instituto Estudios Nucleares, Madrid, and Comision Asesara de Investigacion Cientffica y Tecnica (R.F.A. -E.).A previously published bound on the probability of finding n pions in the dressed nucleon in Chew-Low theory is improved. The proof is then extended to the recently derived cloudy-bag-model Hamiltonian. Together with a bound on the average number of pions (0.9±1.0), our result strongly suggests a rapid convergence of the perturbation expansion in the cloudy bag model.engjournal articlehttp://dx.doi.org/10.1103/PhysRevD.24.1961http://journals.aps.org/open access53Astronomy and astrophysicsPhysicsparticles and fieldsFísica (Física)22 Física
