✦ Synopsis

The yield of a powerful neutron source may be measured in a simple way by means of a very thin detector of slow neutrons placed in a hydrogenated substance surrounding the source. Some of the quantities used in the calculations are discussed in this paper, such as the average-path 8 of a neutron in the thin detector and the average number iV of collisions before capture. The discussion of the latter quantity lead to the question of the reflection coefficient p (albedo) of a plane boundary.

The value of p was found by elementary considerations.
