Abstract
The 12C( 12C, α) 20Ne reaction is studied near E c.m. = 15 MeV. Angular distributions for three energies and excitation functions at θ lab = 30° over an energy range E c.m. = 14.5−15.4 MeV for about 20 levels in 20Ne ( E ex = 0–13 MeV) are examined. The statistical analysis yields the results that a correlated resonance is present at E c.m. = 14.75 MeV. A nonstatistical contribution to the reaction is also apparent when energy-averaged cross sections are compared with the Hauser-Feshbach model predictions. Strong population of the 0 + 3 band in 20Ne is observed.
