Book Description
The scattering of slow neutron beams provides unique, non-destructive, quantitative information on the structure and dynamics of materials of interest in physics, chemistry, materials science, biology, geology, and other fields. Liquid hydrogen is a widely-used neutron moderator medium, and an accurate knowledge of its slow neutron cross section is essential for the design and optimization of intense slow neutron sources. In particular the rapid drop of the slow neutron scattering cross section of liquid parahydrogen below 15 meV, which renders the moderator volume transparent to the neutron energies of most interest for scattering studies, is therefore especially interesting and important. We have placed an upper bound on the total cross section and the scattering cross section for slow neutrons with energies between 0.43 meV and 16.1 meV on liquid hydrogen at 15.6 K using neutron transmission measurements on the hydrogen target of the NPDGamma collaboration at the Spallation Neutron Source at Oak Ridge National Laboratory. At 1 meV this new upper bound is a factor of 3 below the data from previous work which has been used in the design of liquid hydrogen moderators at slow neutron sources. We describe our measurements, compare them with previous work, and discuss the implications for designing more intense slow neutron sources.

Book Description
Solid state physicists have long appreciated the usefulness of thermal neutron scattering in the inves tigation of condensed matter. This technique was first made possible by the advent of the nuclear reac tor and has, since then, undergone many refinements. The developments in this field of research have, we felt, necessitated the making of a comprehensive compilation of the published thermal neutron papers. The large number of titles collected in this book, as well as their diversity and their yearly distribution, reflects the continued contribution of the neutron probe to our understanding of physical systems. This bibliography is an updated and improved version of the one first published by us in March of 1973 under a similar title. Many of the omissions and inconsistencies of the first edition, such as occurred, for example, in the initialing of authors' names, have been corrected. The literature search has been carried back to 1932, the year when the existence of the neutron was experimentally confirmed. Several additional journals have also been searched and brought up to date together with those listed in our first publication. The number of entries is now 8543, an increase of 65 per cent relative to the first edition.
