Abstract
It is proposed to measure the shift in the angular distribution of light charged particles (LCP) in ternary fission caused by polarized neutrons of plutonium isotopes in the resonance region with \(E_{n}=0.264\) eV for the \({}^{241}\) Pu target and \(E_{n}=0.294\) eV for the \({}^{239}\) Pu target. The reliability of interpretation of these experiments will compare favorably with measurements carried out previously at \(E_{n}=4.5\) meV. The advantage is associated with a noticeable weakening of the influence of resonances, the parameters of which may raise some doubts. We are talking about resonances introduced at neutron energies \(E_{n}<0\) eV. In addition, in the region of these two resonances, the fractions of impurity partial cross sections with a spin different from the spin of the resonance itself are small. It is important that the magnitude of the effects expected at the indicated resonance energies will be significantly greater than those previously obtained in the cold energy region.
