Alpha spectra from the triton bombardment of natural nitrogen are studied at laboratory angles of 30 and 90 deg with a double-focusing magnetic spectrometer. Observation of alpha groups from N/sup 14/(t, alpha )C/sup 13/ allows the positions of energy levels in C/sup 13/ to be investigated up to an excitation energy of 12.5 Mev. Levels are observed at 10.736, 10.809, 11.000, values range from 0.020 to 0.030 Mev. Levels at 5.51, 6.10, and 10.47 Mev are not seen. Certain structural features of the alpha continuum underlying C/sup 13/ groups can be tentatively identified with alpha groups from the two-stage reaction wn levels in O/sup 16/ near 15-Mev excitation. Cross sections are reported for various features of the alpha spectra, as well as for corresponding features of the proton spectra. (auth)
