Abstract
The treatment presented in two preceding papers is extended to cover the case of spin-dependent forces. A general theorem is derived which reduces the problem of scattering by spin-dependent forces to the problem of scattering by spin-independent forces, which ahs previously been solved analytically. It is shown that observations on the neutrons returning from the scatterer can be used in many practical cases to determine the ratio of the two scattering amplitudes. Similarly, for very small probability of depolarization per single collision, the depolarization of the neutrons transmitted through the scatterer offers information about the spin dependence of the scattering amplitudes. The necessary material for the evaluation of the observation is presented in table form. A comparison is made with a paper by Borowitz and Hamermesh in which the same subject has been treated by a different method.
