Elastic scattering of alpha particles by C__

The cross-section for the elastic scattering of alpha particles by 013 was measured for E^ = 2.0 MeV to E^ = 3.5 MeV at center of mass angles 169.6°, 142.6°, 107.9°, and 54.7°. Analysis of these excitation curves allowed assignment of parity to 8 states of 017. Relative parities from the C13( ^ ,n)016 angular distribution analysis allowed assignment of parity to two additional states. A discrepancy was noted in the spin assignment of one state (Ex = 8.195 MeV). Assignments of parity and of two possible spins were made to this state and to one state not observed in the C13( ^ ,n)016 cross-sections. The assignments made, together with the excitation energies in 017 of the states are 7.929, 1/2 8.071, 3/2+; 8.195, 3/2-; 8.317, (3/2, 5/2)-; 8.388, 5/2-; 8.450, 7/2+; 8.489, (3/2, 5/2)-; 8.685, 3/2-; 8.867, 3/2+; 8.875, (9/2, 7/2)-; 8.924, (7/2+)
