Resonances in the excitation functions of the alpha-particle and proton exit channels of the16O +12C system near the coulomb barrier

Experimental Evidence forα-Particle Doorway States in theC12+Voit1, Ischenko2, Siller3 1973Phys. Rev. Lett.Self Cite

“…We believe that the following interpretation of the experimental results could be made: In the 12 C + 12 C reaction a-particle doorway states arise at the resonance energies £ c .m. = 5.7, 6.0, and 6.3 MeV.…”

“…Twelve years ago three marked resonances were found in the excitation functions of the a, p, n, and y yields of the reaction 12 C + 12 C just below the Coulomb barrier. 1 The resonances at E cnu = 5.7, 6.0, and 6.3 MeV were correlated among all angles and exit channels.…”

“…The self-supporting 12 C targets were about 10 to 15 Mg/cm 2 thick. The linear solid angle of the detectors was about ± 1.5°.…”
