摘要：

A method for generating neutron packs by means of a chopped spin-flip-device in connection with a polarized-neutron spectrometer is described. The duration and the repetition rate of the neutron-packs can be determined over a wide range electronically. The resolution Δt/t or Δλ/λ is 3.3% amd may be improved without any loss of intensity to better than 1%. For repetition rates higher than 5000 c/s, the peak intensity is higher than the peak intensity obtained with comparable mechanical two-chopper-systems. The described method is specially suited for measuring small changes of neutron energy. © 1968.
