Abstract
Experiments in the field of neutron interferometry can be interpreted in terms of a neutron phase-echo concept, which is closely related to the spin-echo concept. Phase echo analysis can be done even with unpolarized neutron beams if coherence between separate beams exists. Furthermore a method is proposed for a dynamical polarization of a neutron beam due to the combination of a momentum separation and a spin overlapping part. This system consists of a multistage h.f. flipper and one half of a spin-echo spectrometer and allows an optimal use of available neutrons.
