| Abstract: | Time dependent magnetic fields can be used to produce exact rotations of spin wavefunctions. This avoids the inherent approximations encountered in experiments performed with static fields to demonstrate the effect of 2π-rotations on fermions. Two of the experiments proposed explicitly will use forthcoming interferometers for ultra cold neutrons. |
