INVESTIGATION OF THE MECHANISM OF THE REACTION N-15(ALPHA,T)O-16 AT E-ALPHA=30.3 MEV BY THE METHOD OF ANGULAR T-GAMMA CORRELATIONS

The double-differential cross sections for the reaction N-15(alpha, t gamma)O-16 at E-alpha = 30.3 MeV were measured for triton emission ang les lying in the range between 18 degrees and 160 degrees. All even sp in-tenser components of the density matrix for the final nucleus are r econstructed in a model-independent way. The angular dependences of th e population of magnetic substates of the 3(-) 6.131-MeV state are pre sented together with the components of the orientation tensor for mult ipole moments of this state. Experimental data are compared with the r esults of calculations performed by assuming the nucleon-stripping mec hanism, which is taken into account by the coupled-channel method, and the mechanism of compound-nucleus production.
