Zusammenfassung:It is shown that Р-even Т-odd asymmetries in the analyzed reaction components of total cross sections depend linearly on neutron vector of polarization . Experimental values of these correlators are restored using experimental values of coefficients of asymmetry . Agreement between experimental and theoretical values of the ternary and quintuple correlators considered above during the escape of alpha particles, prompt neutrons, and gamma quanta, is demonstrated using angles of rotation calculated on the basis of . The triple correlator for the escape of alpha particles for the 233 U target nucleus was calculated with allowance for the effect of the rotation of a compound fissile nucleus (CFN) around its axis of fission, due to violation of the axial symmetry of the CFN and the collective bending vibrations of the nucleus in the vicinity of the point of its discontinuity.
