Abstract : The helium 3 sandwich-type spectrometer has proved to be an extremely good detector for making neutron spectra and attenuation measurements. A method of procedure is outlined to demonstrate how neutron relaxation lengths can be measured easily and how this technique can be applied to other neutron measurement problems. (Author)
