N recent publications' ' we reported the formation of the nuclides 99 5', 99 ', and 10025 by intense neutron bombard- ment of plutonium and higher-mass nuclides. Further observa- tions of the nuclear properties of these nuclides have now been made, using, in some cases, samples of higher activity prepared in new neutron bombardments. ln addition, a 15-hour alpha- emitting isotope of element 100 has been observed in the products of the neutron bombardment of plutonium.
