      Results of comparing various isotropizations of group scattering constants are given. A special attention is paid to studying effects of arising negative transport constants. A simple way to overcome negativity is proposed. Computational results are supplied allowing to formulate most desirable way of isotropization for fast neutron transfer applications.
