Ú
Neutron
A subatomic particle with no electric charge, usually found in the
Ú
of atoms. Neu-
trons bound in nuclei are stable, free neutrons, however, undergo beta
with a mean
lifetime of about 12 minutes. Free Neutrons having different energies are categorized by the
Ú
Neutron Temperature
.
Neutron Detection
Thermal neutrons (
Ú
Neutron Temperature
) can be detected by observing their interac-
tion with
like
3
He (
Ú
),
6
Li,
10
B, or
157
Gd. These interactions produce
Ú
or
Ú
Gamma Radiation
which is subsequently detected. To detect fast
neutrons (
Ú
Neutron Temperature
), a
Ú
must be applied.
Neutron Temperature
An energy scale for free
Ú
Neutrons
. The most important categories are fast neutrons, having
an energy substantially above 1 eV, slow Neutrons, with an energy below 0.4 eV and thermal
neutrons yielding an energy about 0.025 eV. Fast neutrons are deccelerated or thermalized
by a
