Abstract
Using the improved non-relativistic quark model for light baryons, we follow up an old suggestion due to S. L. Glashow that there might exist a relatively strong tensor mixing in the ground state of the nucleon. We find that, except for the ratio of the charge radii of the neutron and the proton, Glashow's proposal is consistent with the empirical values of a series of baryonic observables that could be sensitive to this mixing. The origin of the mixing itself remains obscure, in the framework of the model used in this paper.
