The strong interactions are charge independent. If we limit ourselves to the strong interactions, we have the isospin T as a good quantum number. Here, we consider the lack of level repulsion of states of different isospin and how this effect manifests in nearest neighbor spacing (NNS) histograms, which provide a visual and statistical context in which to study distributions of energy level spacings. In particular, we study nucleons in the f - p model space for the nucleus 44Ti. We also compare NNS distributions produced in the isospin formalism to distributions produced in the proton-neutron formalism.
