Neutron-Scattering Measurements of 'Soft Matter'

摘要

Neutron scattering had its origin in 1932, the year that marked the discovery of the neutron by Chadwick, and the first nuclear reactors were successfully oper- ated in Chicago and Oak Ridge, Tenn., In the early 1940s. during its initial stages, neutron scattering was used mainly for the study of "hard" crystalline materials. For example, Shull and wollan's pioneer- Ing research, which led to the 1994 Nobel Prize in physics, began with studies of Iron, chromium, and iridium, and was Followed by the development of polaria- Tion analysis to determine the structure Of magnetic materials.
