Abstract
IT is known that some nuclei have very large capture cross-sections for slow neutrons. This fact may be explained from the point of view of wave mechanics, which also leads to the consequence that the capture cross-section should decrease with 1/v with increasing velocity of the neutrons, so long as the capture probability is constant over the velocity region concerned.
