  An approach is developed, which essentially simplifies derivation of kinetic
equation for polarization in non-relativistic scattering. This approach is
applicable for collision of projectile particles with a target for any spins of
colliding particles. The most detailed consideration is performed for the case
of spin 1/2 projectile particle interacting with spin 1/2 particle of a target.
The solution of the kinetic equation for the case of zero initial polarization
is presented.
