Neutron detection
Neutron detection is the effective detection of neutrons entering a well-positioned detector.
There are two key aspects to effective neutron detection:
Neutron probe
emitted by the decay of the americium collide with the light beryllium nuclei, producing fast neutrons. When these fast neutrons collide with hydrogen
Neutron temperature
medium (neutron moderator) at this temperature, neutrons arrive at about this energy level, provided that they are not absorbed. Thermal neutrons have a
Nested neutron spectrometer
thermal neutron energies.
In order for a higher energy neutrons to be detected their energies must be decreased, or "moderated".
To slow down neutrons at higher
Explosive detection
scattering from fast neutrons to produce detectable gamma rays, as opposed to simple absorption occurring with the thermal neutrons), but these modifications
Neutron
the neutron is included in the table of nuclides.
Within the nucleus, protons and neutrons are bound together through the nuclear force, and neutrons are
Ultracold neutrons
Ultracold neutrons (UCN) are free neutrons which can be stored in traps made from certain materials.
The storage is based on the reflection of UCN by such
Neutron activation analysis

The sample is bombarded with neutrons, causing the elements to form radioactive isotopes
Neutron capture
Neutron capture is a nuclear reaction in which an atomic nucleus and one or more neutrons collide and merge to form a heavier nucleus. Since neutrons
Prompt neutron
adjoint neutron flux.
This concept arises because delayed neutrons are emitted with an energy spectrum more thermalized relative to prompt neutrons.
Neutron flux
nearly equivalently number of neutrons travelling through a unit area in unit time.
The neutron fluence is defined as the neutron flux integrated over a certain
