Two neutron sciences

JUN 01, 1966

Improvements in sources, detectors, models and data analysis have produced a flood of neutron‐cross‐section information. Drifting farther and farther apart in the flood are measurers of cross sections and designers of neutron devices. The result has been two sciences instead of one.

NEEDS FOR MICROSCOPIC neutron data in nuclearenergy applications have continued to expand over the years. The last two decades have seen steady and at times dramatic progress in the detail and extent to which neutron cross sections can be measured or calculated. Pulsed neutron sources, with associated time‐of‐flight techniques, now dominate almost all energy ranges from fractions of an electron volt to many millions of electron volts. Concurrently, improved detectors such as large liquid scintillator tanks have been developed, and on‐line computers have been designed to manage and analyze experiments involving many parameters.
