Abstract
The moderation of pile neutrons to very low energies has been investigated. Liquid hydrogen, liquid hydrogen deuteride and methane at 20°k were found to be effective moderators. After an examination of the safety aspects, a volume of liquid hydrogen was maintained at the centre of a reactor, and the velocity spectrum of neutrons scattered from it was measured. Appreciable moderation of neutrons to very low energies was observed. By this method it is practicable to increase considerably the flux of cold neutrons in a beam. Thus, in the present experiment the flux of 10 Å wavelength was increased by a factor of 26.Keywords
