Sizes of baryon confinement regions

Arguments are presented that R congruent 0.5 fm; more specifically, θ(R) = π/2, where θ(R) is the chiral angle at the bag radius R, is appropriate for quark substructure of the nucleon. This cuts off the boson exchange potential at momentum ΛχSB congruent 1 GeV. For this division, half of the baryon number lies in the interior region and half in the exterior. For strange baryons with little pion cloud to compress the confinement region, R may be 1-1.1 fm as in the M.I.T. bag model. For this radius, a good phenomenology results for magnetic moments. On the other hand, the Callan-Klebanov model, which is also successful, corresponds, as the skyrmion, to R→O
