Abstract
ONE of the best methods of collecting radioelements free from any inactive material is the application of an electric field, either to the gaseous or liquid phase. Well-known examples of the former process are the collection of the active deposits produced by the three emanations; of the latter, the electrolytic deposition of these and other isotopes of lead, bismuth and polonium. It seemed worth while to investigate whether an electric field might also be of help in concentrating the newly discovered artificial radioelements. Especially interesting is the question as to their possible charge when produced in gases by fast and slow neutrons.
