    "abstract": "We consider a simplified model for resonant neutron-nucleus interaction with\ncoupled channels. An analytical solution is given for two coupled channels and\narbitrary neutron orbital momentum. A case of a week channel coupling,\ncorresponding to narrow Breit-Wigner resonance, is analyzed in details. As far\nas the total width of a resonance coincides with the neutron width, the model\nis directly appropriate only for light nuclei. We study a mixing of two narrow\ns- and p-wave resonances by P- and P-,T-noninvariant potentials in the first\norder of perturbation theory. As an example a close-lying pair of s- and p-wave\nresonances of the $^{35}$Cl nucleus is considered. The favorable possibilities\nare shown to exist on thick targets for measurements beyond the resonance\nwidths. In particular, an interference minimum near s-wave resonance is of\ninterest for P-odd neutron spin rotation on light spinless nuclei.",
