Abstract
The mean squared slowing-down distance, <r(2)>,and the age to thermal capture (Migration Area), M(2), direct measures of the slowing-down, a nd the spreading out, processes of neutrons in a medium. They also ent er directly into reactor calculations. These parameters have been dete rmined experimentally for Am-Be neutrons (mean energy 4.46 Me V), in a block of perspex, using the activities induced in thin indium foils f rom the In-115(n/gamma)In-116 reactions.
