Identification of nonclassical states in neutron spin precession experiments

Highly non-classical states are produced in polarized neutron spin precession experiments due to the coherent superposition of spin-up and spin-down states. These states are described within the Wigner function formalism and the measured momentum modulation in a neutron spin precession experiment is taken as a sign of such non-classical states.
