“…There is also a sixth member of this series, known as uranium Y ( 46), ( 50), ( 56), (59), which was discovered in 1911 by G. N. Antonoff, who was working under Sir Ernest Rutherford at the University of Manchester. He afterward returned to St. Petersburg.…”

In 1898 there was discovered an element, radium, which continually and, spontaneously emits light, heat, and other radiations. Investigation of these astonishing phenomena by the Curies and many others has revealed about forty interrelated radioactive elements which, like radium, are unstable. They do not, however, occupy forty places in the periodic system, but are crowded into only ten places. The explanation for the existence of these numerous so-called "radioactive isotopes" and their genealogical descent from uranium and thorium were discovered widependently by K. Fajans, F. Soddy, A. S. Russell, and A. Fleck. Since the original literature on the radioactive elements embraces such a vast field of research, the following account of their discovery is necessarily far from complete. "Radium is not to enrich any one. It is an element; it is for all people" (1)."So the atoms in turn, we now clearly discern, Fly to bits with the utmost facility; They wend on their way, and, in splitting, display An absolute lack of stability" (2).

“…In 1911, Antonoff (1911) had separated uranium Y À UY ( 231 Th) from a purified U solution. UY was chemically similar to Th and Antonoff (1913) suggested that this might be the point at which the Ac series branched off from the U series.…”
