The theory of angular distributions and correlations is described. Some new tables of Clebsch-Gordan coefficients have been calculated. In addition, particle and [gamma]-ray radiation functions are tabulated. Distribution and correlation functions for two particles of spin 1/2 coming together to form a compound nucleus which successively emits an [...]particle and then [gamma]-ray are tabulated for a large number of spins of the excited states involved.

Several angular distributions from the reaction N[superscript 15]([...])C[superscript 12] were measured using scintillation counters as detectors. The analysis of the data shows that the 12.51-Mev level of O[superscript 16] is 2- or greater than five, that the 12.95-Mev level of O[superscript 16] is 2- or greater than five, that the 13.24-Mev level of O[superscript 16] is 4+ or greater than five, and that the 4.43-Mev level of C[superscript 12] is 2+ or greater than four.
