Pseudomagnetic effects for resonance neutrons

A general theory of pseudomagnetic effects on the propagation of polarized neutrons through a polarized target using a multiresonance approach is presented. Some applications related to proposed searches for time-reversal invariance violation in neutron scattering are considered.
