摘要：

We show that upper bounds exist on the density of neutrons that can be moderated to a specified energy from an intense pulsed source of fast neutrons. Expressions are derived for the maximum density in the following cases: (a) a uniform injection of fast neutrons into an infinite moderator, (b) a localized central source in a finite heavy atom moderator, and (c)a point source in an infinite hydrogenous moderator. Correspondingly, upper bounds are given for the rates of single- And multiple-resonance neutron capture.
