The Na/sup 23/, alpha )Ne/sup 20/ reaction has been studied for proton bombarding energies in the range 100 to 450 kev. Four narrow resonances were observed at proton bombarding energies E = 286, 338, 374, and 445 kev. Excitation functions were taken at each of these resonances, and the alpha yield, width, and resonance energy were determined for each resonance. On the basis of angular distribution measurements, spin and parity assignments have been made for the resonances at E/sub p/ = 286, 335, and 374 kev. Upper limits have been estublished for the nonresonant cross-section factor S and for the alpha yield from resonances not observed. The Na/sup 23/(p, alpha ) Ne/sup 20/ reaction rate in stars is computed for temperatures (5-- 10) x 10/sup 8/ deg K, the temperature range in which carbon burning takes place. (auth)
