Determination of intermediate nucleus polarization in the three-particle reaction of step-by-step type

Methods, using no simulation, for finding statistic tensors of polarization (STP) according to a set of experimental values of the angular correlation function by means of the computer program complex designed for this purpose are suggested. Three-particle reaction of sequential type a0+A0→a1+A1, A1→a2+A2 is described. General peculiarities of application of the program complex are illustrated by the experimental data on the reaction 6Li(α,α'd)4He proceeding through isolated resonance 2.184 MeV, 3+ of the 6Li intermediate nucleus, and the 7Li(α, α't)4He reaction proceeding through isolated resonance 4.63 MeV, 7/2- of the 7Li intermediate nucleus. Analysis of calculated and experimental results shows the necessity of thorough selection of geometry of the correlation experiment at the stage of its planning
