Abstract : An analysis is made of the angular distributions of the 4.43 Mev gamma radiation following C12(P1, P2 gamma)C12 in the vicinity of the two resonance peaks at bombarding energies 5.36 Mev and 5.89 Mev. It is shown that the angular distributions of such gamma radiation are strongly dominated not only by two resonance levels (3/2+ and 5/2+), in N13, with excitation energies 6.91 Mev and 7.42 Mev (called C and E) respectively, which correspond to the two resonance peaks, but also by another lower level (5/2+) with 6.38 Mev (called A) and their interference. A better fit between the theory and experimental data is obtained for reduced width amplitude ratios of -2.3 and -0.32. Finally, the effects of other neighboring levels in N13 are considered.
