✦ Synopsis

Neutron resonance spin echo (NRSE) spectroscopy enables us to measure neutron quasielastic scattering with high-energy resolution. It is desirable to apply NRSE spectroscopy to pulsed neutron sources because this application allows a very wide range of the spin echo time. We have already developed the neutron resonance spin flipper applicable to a polychromatic pulsed neutron beam, which is necessary for the TOF-NRSE method. Using this flipper, we have succeeded in observing spin echo signals with visibility higher than 0.65 for the pulsed neutron beam with wavelength from 0.3 to 0:9 nm: We discuss the prospect of the NRSE spectrometer with high-energy resolution on the basis of the present result.

It is well known that upon passage through a spatially alternating transverse magnetic field, produced by a meander-shaped conducting foil, in its rest frame each neutron creates its individual frequency which depends on its velocity and the period of the meander.

We report an experimental demonstration of the "bootstrap" technique for neutron resonance spin echo (NRSE), whereby the effective relative precession angle of the neutron spins can be increased by a factor of 2N with respect to Larmor precession in the same static magnetic field. In the present cas
