Abstract
We have examined both the elastic scattering of alpha particles in nitrogen as a function of the energy between 1.5 and 3.5 Mev at 90°, 125°16′, 137°43′ and 156°20′ (center of mass), and the cross section for the reaction at 90° (lab) in the same energy region. Two new resonances at Mev and Mev correspond to levels in at excitation energies of 6.69 Mev and 6.85 Mev, respectively. These same levels were found to emit protons as well, leading to the ground state of . The () reaction has a relative probability of about 5 percent for the upper level and 0.3 percent for the lower level, compared to the elastic scattering.
