OSTI ID:4298161
The life of a fast neutron in a moderating medium may be divided into two parts: At first it is slowed by collisions with the nuclei of the inedium, then, when its energy is in the thermal range, it diffuses until its capture. The determination of the distribution of therinal neutrons from the distribution of fast neutrons is examinined on the basis of the distribution of nascent thermal neutrons and the law of scattering. The graphite used as the moderator was of such size that it would be considered infinite. (J.S.R.)
