    "abstract": "Using the difference between the gauge symmetric and standard pi-N-delta\ncouplings, a contact pi-pi-N-N term, quadratic in the pi-N-delta coupling, is\nexplicitly constructed. Besides, a contribution from the delta excitation\nmechanism to the photon spectrum for the radiative muon capture in hydrogen is\nderived from the gauge symmetric pi-N-delta and gamma-N-delta couplings. It is\nshown for the photon spectrum, studied recently experimentally, that the new\nspectrum is for the photon momentums k \u003e 60 MeV by 4-10 % smaller than the one\nobtained from standardly used couplings with the on-shell deltas.",
