Slow Neutron Capture for Elemental Analysis, INTERNATIONAL ATOMIC ENERGY AGENCY, Vienna, Austria, 2006.
In a recent paper (1) the reaction of
slow neutrons with gasous [.sup.3]He was studied experimentally and it was estimated that that in the experiment 46 Lyman alpha photons were produced for each
slow neutron (wave-length 0.496 nm) absorbed in a chamber containing [.sup.3]He at a pressure of 93 kPa.

David Lochbaum, nuclear safety engineer for the Union of Concerned Scientists (UCS), says that the pebble bed reactor uses blocks of graphite to
slow neutron action, although "graphite is a form of carbon, which can ignite in a reactor fire.

slow neutron physics T.
Building on this success, a
slow neutron MicroMegas detector has been developed by a team (including some of the authors of this paper) at ORNL [5],[6].
Gentile, [.sup.3]He Spin Filters for
Slow Neutron Physics, this Special Issue.
Achieving and maintaining the highest [.sup.3]He polarization in a neutron spin filter can have a significant impact on the feasibility of a long term experiment in
slow neutron physics.
When using
slow neutrons in the reactor for these purposes, their energy is ~0.025 eV [1, 3].
In 1938 he received the Nobel Prize in Physics "for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by
slow neutrons" (1, 2).

slow neutrons," Physical Review D, vol.
If D or T molecules are combined chemically with one oxygen atom we get heavy water which is used as stopper of fast neutron in fission reactors, so that fissionable uranium ( ) can be broken by the stopped neutrons usually known as
slow neutrons. In ordinary hydrogen atom the minimum possible constant distance between proton and the revolving around it electron is 10-8cm, usually know as s-wave approximation or Bohr's first orbital radius also know as K-shell radius.
