Abstract

Angular distributions have been measured for the reactions C12(N14, Be9)F17, C12(N14, B10)O16, and C12(N14, C12)N14 at E14N=53 MeV, and compared to Hauser-Feshbach predictions. Additionally, excitation functions for C12(N14, Li6)Ne20 and C12(N14, B10)O16 in the region of 53 MeV have been taken. The reactions which involve Be9 and B10 are well fitted by the Hauser-Feshbach theory, indicating these products are formed via a compound nuclear reaction. The relative cross sections between the discrete states populated in Be9 + F17 and B10 + O16 are best described by a critical angular momentum between 14 and 15. The magnitude of the C12(N14, C12)N14 reaction is poorly described by Hauser-Feshbach theory, indicating a noncompound nature for this reaction channel.
