10 LIVRES EN ANGLAIS EN RAPPORT AVEC «SLOW NEUTRON»
Découvrez l'usage de
slow neutron dans la sélection bibliographique suivante. Des livres en rapport avec
slow neutron et de courts extraits de ceux-ci pour replacer dans son contexte son utilisation littéraire.
1
Radiation Detection and Measurement
This is conventionally called the slow neutron region and is distinguished from
intermediate and fast neutrons with energies above this value. Slow neutrons are
of particular significance in presentday nuclear reactors and much of the ...
Hence, fast neutrons must be moderated to slow neutron energies to increase the
probability of neutron capture. Fast neutrons can be efficiently moderated by
elastic collisions with hydrogen in hydrogen-containing materials, e.g., water, ...
William H. Hallenbeck, 1994

Experimental Techniques in Nuclear and Particle Physics
7.1 and 7.2 rely on the very large cross section for slow neutron capture by
certain isotopes. Without the addition of a moderator, these detectors are not well
suited for detecting fast neutrons. The elastic cross section for fast neutrons is
large in ...

Practical Applications of
Neutron Radiography and Gaging
3 and are based on fast neutron moderation. In the transmission gage three
choices are available: fast neutron source — fast neutron detector; slow neutron
source — slow neutron detector; or fast neutron source-slow neutron detector (
which ...
Harold Berger, Symposium on Practical Applications of Neutron Radiography and Gaging, ASTM International, 1976

Nuclear Methods in Science and Technology
We will also discuss in this chapter cold and ultracold neutrons, particularly since
these are gaining increasing popularity as a tool for basic and applied studies of
matter. 6.1 Neutron sources There are a variety of ways in 211 Slow neutron ...

International Trends in Applied Optics
Section 22.3 will discuss physical and qualitative features of slow neutron
propagation in neutron fibers. Section 22.4 will present a summary of boron-
neutron capture therapy and discuss a possible application of neutron fibers to it.
Section ...
Arthur Henry Guenther, 2002

Handbook of Soil Science
3.2) is usually linear and relates 9V to slow neutron counts or count ratio (CR): 9v
=a + b(CR) [3.6] where CR is the ratio of slow neutron counts at a specific
location in the soil to a standard count obtained with the probe in its shield. For
many ...
The number of the prompt neutrons depends on the place where the slow
neutron is accepted and the phase of the nucleons oscillation. The structure of
the zone where the slow neutron must be accepted to provoke the fission of
nucleus is as ...
As 6LiF pellets are only sensitive to thermal neutrons, slow neutron
measurements have been performed using bare pellets. For higher neutron
energy measurements, the pellets have been inserted in polythene blocks. A
calibration has been ...
10
Atoms, Radiation, and Radiation Protection
We discuss slow-neutron detection methods first. Table 10.2 lists the three most
important nuclear reactions for slow-neutron detection. The reaction-product
kinetic energies and cross sections are given for capture of thermal neutrons (
energy ...
