Element No. 93

Abstract

THE Rome correspondent of the Times states, in a short communication published in the issue of June 5, that an article in the Goiornale d'ltalia which surveys recent work on induced radioactivity by Prof. Enrico Fermi, of the Royal University, Rome, includes the announcement that Prof. Fermi has produced a new element, of atomic number 93. The new element was found when uranium, atomic number 92, was bombarded with neutrons; it is radioactive, with a half-period of about 13 minutes. This announcement would appear to be a sequel to the experiments reported by Prof. Fermi in NATUEE of May 19, p. 757, when he described the effects of bombarding various elements with a powerful stream of neutrons. Uranium was not among the elements mentioned by Prof. Fermi in his communication, but it would seem that he has now succeeded in obtaining an effect from it.
