Parameters of the 9.17 MeV level in 14N

Mutually consistent measurements of elastic proton scattering and resonance absorption show that the width of the 9.17 MeV level in 14N (Γ=135±8 eV) is almost twice as large as the accepted literature value. The positive parity is unambiguously confirmed. The excitation energy is determined to be 9172.5±0.3 keV, based upon a cascade-crossover technique with a 56Co source for calibration. The expected azimuthal asymmetry of the resonance fluorescence of the plane-polarized photons at this resonance is demonstrated quantitatively
