Abstract

The 7.03-MeV state in N14 has been excited by resonance scattering of the Doppler-broadened 7.115-MeV radiation from the F19(p, αγ)O16 reaction. The measurement of the resonance effect as a function of the angle between the proton beam and the γ rays incident on the scatterer gives a cutoff angle which corresponds to a level energy of 7.029±0.006 MeV. The angular distribution of the scattered radiation is consistent with a spin of 2, a fit being obtained for a quadrupole-dipole amplitude ratio of -0.60±0.15. Assuming all the decays of this level are to the ground state, the mean life of this level becomes (5.4±0.5)×1015 sec.
