Neutron capture - Wikipedia, the free encyclopedia
Neutron capture is a kind of nuclear reaction in which an atomic nucleus collides with one or more neutrons and they merge to form a heavier nucleus. Since neutrons have no electric charge, they can ...

Neutron absorption is the main activity which controls the rate of nuclear fission in a reactor - the 235U absorbs thermal neutrons in order to fission, and produces other neutrons in the process to trigger other fissions in the chain reaction.

Ceradyne recently formed a manufacturing division that offers two leading materials for neutron absorption applications: BORAL® and Aluminum/Boron Carbide Metal Matrix Composite (AL/B4C MMC). Our new division, Ceradyne Canada, is based in Chicoutimi, Quebec and is the result of two acquisitions: BORAL® purchased from...

The absorption casing for the absorbing of radioactive radiation and fission products comprises four layers of different materials which retain the various kinds of radiation and the gaseous fission products. ... The second layer (38) serves for the absorption of neutron radiation and consists of boron, hafnium,

By-passed Nuclei are proton rich nuclei which cannot be produced by the neutron absorption process. They may have been produced by proton absorption, neutron emission (due to the absorption of a gamma ray by the nucleus, for example) or an inverse beta process caused by the absorption of a positron in the nucleus...
