EFFECT DUE TO NEUTRON CAPTURE
The important information in this chapter is summarized below.
Effect Due To Neutron Capture Summary
Dislocation of an atom due to emission of radiation
Highly energetic recoil nuclei are produced indirectly by the absorption
of a neutron and subsequent emission of a g-ray . When the g-ray is
emitted, the atom recoils due to the reaction of the nucleus to the g-ray's
momentum (conservation of momentum).
Effects from capture
Introduction of impurity atom due to the transmutation of the absorbing
Atomic displacement due to recoil atoms or knock-ons
Thermal neutrons cannot produce displacements directly, but can indirectly as a
result of radiative capture and other neutron reactions or elastic scattering.
