Abstract
Excitation functions of the reaction /sup 12/C(/sup 12/C,..cap alpha..)/sup 20/Ne have been measured in 50-keV energy steps from E/sub c. m./ = 4.0--8.0 MeV at 15 angles between theta/sub c. m./ = 6degree and 90degree. From the angle-integrated cross sections of the first six transitions to /sup 20/Ne the following resonance energies have been deduced: E/sub c. m./ = 4.25, 4.46, 4.62, 4.88, 5.0, 5.64, 5.92, and 6.25 MeV. The spin-parity assignments for these resonances have been determined to be 0/sup +/, 4/sup +/(2/sup +/), 2/sup +/, 2/sup +/, 2/sup +/, 2/sup +/, 4/sup +/, and 2/sup +/, respectively.
