Induced Radioactivity with Neutrons from Slow Deuterons

Abstract

IT is of interest, not least from the point of view of possible practical applications, to search for the lower limit of voltages, with which artificial radioactivity can still be produced of intensity sufficient for utilization. We have begun an investigation, in which the induced activity is produced by neutrons, which are produced by slow deuterons. This procedure has the advantage that the small number of neutrons that can be expected will be compensated, at least partly, by the greater efficiency of slow neutrons, due to the slow primary particles.
