摘要：

A new method for the accurate determination of the degree of polarization of a neutron beam which has been polarized by transmission through a spin polarized He-3 cell is given. The method does not require the use of an analyzer or spin flipper nor does it require an accurate independent determination of the He-3 polarization. The method provides a continuous on-line determination of the neutron polarization. The method may be of use in the accurate determination of correlation coefficients in neutron beta decay which provide a test of the standard model for the electroweak interaction. The method may also provide an accurate procedure for the calibration of polarized He-3 targets used in medium and high energy scattering experiments.
