摘要:

Neutron Resonance Spin Echo (NRSE), also called Zero Field Spin Echo, is a spin echo technique that replaces the long high field precession coils of conventional spin echo (NSE) (1) with field free regions bounded by magnetic resonance flip coils (2,3). One advantage of the method is that it is easily adapted to use the tilted field technique first proposed by F. Mezei (1) for high resolution measurement of phonon linewidths and by R. Pynn (4) for high resolution elastic small angle scattering. The relatively small r-f flipper coils can be readily tilted through rather large angles.

摘要:

At the Hahn-Meitner-Institut in Berlin, Germany, the first Bragg reflections from a nuclear antiferromagnetic state in silver have recently been observed. The results were obtained by an international research team, in an EC-supported collaboration between the Helsinki University of Technology, Finland, Risø National Laboratory, Denmark, and the Berlin Neutron Scattering Center at the Hahn-Meitner-Institut Berlin.

摘要:

The use of smooth, hollow glass capillaries for neutron optics was discussed elsewhere (1,2,3). By means of such capillaries, neutron lenses were constructed, which allowed an increase of neutron flux at the focal point by a factor of 10–15. However, up to now the transmission of capillary systems was rather poor; for example, the flux enhancement for the neutron lenses should be at least two orders of magnitude more than observed. The same conclusion comes from direct measurements of the transmission of curved capillaries (3).
