Extract

The paper is concerned with the influence on the effects produced by slow neutrons, of the temperature of the medium in which they are slowed down, attention being focussed on those neutrons which pass freely through cadmium. Results obtained by Arsenjewa-Heil, Heil and Westcott (10) had appeared to show that the groups A and B responsible for activating silver had energies low enough to be affected by temperature. In the present work, a confirmation of the change for group B has been obtained, and a similar effect has been observed with a boron detector. It is suggested that the explanation of the results is that cadmium transmits neutrons of energies down to about 0·2 e. V., and that “group B” is inhomogeneous. During the course of the work, a study of the conditions under which reproducible results could be obtained was undertaken.
