Abstract
The coherence properties of a neutron are analyzed by making use of the Wigner quasi-distribution function. We discuss, in particular, highly non-classical, SchroK dinger-cat-like neutron states that can be obtained in an interferometer or in a magnetic field. The dephasing and decoherence e!ects are quantitatively defined by introducing a `decoherence parametera, that enables one to emphasize some peculiar aspects of irreversibility and decoherence in neutron scattering.File in questo prodotto:
