Abstract

The mean squared slowing-down distance, <r 2>, and the age to themal capture (Migration Area),M 2, are direct measures of the slowing-down, and the spreading out, processes of neutrons in a medium. They also enter directly into reactor calculations. These parameters have been determined experimentally for Am-Be neutrons (mean energy 4.46 Me V), in a block of perpex, using the activities induced in thin indium foils from the115In(n,γ)116In reactions.
