Abstract

FERMI and his co-workers have pointed out that if a neutron source is surrounded by a material rich in hydrogen the neutrons lose energy to the protons on collision, and, after about twenty impacts, their energies are reduced to the order of those due to thermal agitation. They tried to discover whether temperature affects the density of such a neutron ‘gas’ by measuring the activation produced in rhodium by a neutron source surrounded by hydrogenous substances at room temperature and at 200° C. No difference in activation was detected1.
