Neutron Diffraction Study Of Natrolite

Abstract

'ieutron diffraction experiments -’Pre first performed over 25 years ago. Klsasser augmented in 1936 that neutrons could be diffracted by solids, and thio was demonstrated experimentally in the same year by hnlband and Frehwer1', and Mitchell and Powers, using radium-boryllium neutron sources. Those early experiments proved that neutrons.. were diffracted by solids, but did not give quantitative data since the available neutron sources were of very 1o-t intensity. Since intense neutron beams have become available from nuclear reactors, the propertiea of neutrons have been extensively used to study the solid state. The equivalent wavelength for low energy neutrons is given by de Broglie’s equation
