(Gd), helium (³He), lithium (⁶Li), and boron (¹⁰B) exhibit strong neutron absorption due to nuclear resonance effects. The likelihood of absorption increases with neutron wavelength (?_a ? ?), meaning slower neutrons are absorbed more readily than faster ones.

Instrumental and sample requirements

The technique requires a source of neutrons. Neutrons are usually produced in a nuclear reactor
