Abstract
General expression for differential cross section of neutron induced fission is derived with account of arbitrary spin orientation of colliding particles. A covariant description of angular dependence of fission cross section is proposed. Helicity representation for fission fragments is considered in details and limits of its validity are investigated. It is shown that this representation makes reliable basis for description of interference effects in total and differential cross sections of fission induced by slow neutrons. A relation between total fragment helicity K̃ and A.Bohr quantum number K is discussed.
