“…After the discovery of the α-emitting 0.9 ± 0.2-s 263 Sg by Ghiorso et al [129] with a cross-section on the order of 0.3 nb, Druin et al [130], had reported observation of a 0.64 -0.18 +0.32 s SF activity, which they assigned to 263 Sg with 0.6 nb cross-section at 95 MeV. This was thought to be the origin of the fission tracks in the fused silica column of Zvara et al [57], which were made visible by etching with HF subsequent 5-cm segments of the column and scanning the surface with an optical microscope.…”

Names of countries given after Members' names are in accordance with the IUPAC Handbook 1998Handbook -1999. Republication Abstract: In this paper, the chemical properties of the transactinide elements rutherfordium, Rf (element 104); dubnium, Db (element 105); and seaborgium, Sg (element 106) are critically reviewed. The experimental methods for performing rapid chemical separations on a time scale of seconds are reviewed, and comments are given on the special situation with the transactinides for which the chemistry has to be studied with single atoms. There follows a systematic description of theoretical predictions and experimental results on the chemistry of Rf, Db, and Sg-their mutual comparison and evaluation. The literature cited has the cutoff date of March 1999. The more recent chemical identification of bohrium, Bh (element 107), and of hassium, Hs (element 108), should be evaluated in a future Part II of this report.

“…Subsequent α particle decay and spontaneous fission events were recorded in this array and in eight detectors arranged in a box configuration around the implantation detector. Berkeley-Livermore [135] and from Dubna [136] was essentially contemporaneous. The Dubna work is highly important for later developments but does not demonstrate the formation of a new element with adequate conviction, whereas that from Berkeley-Livermore does" [11,45].…”

“…Since the atomic number (Z ) and mass number (A) of the daughter nuclides are known, the parent atomic number and mass number will simply be that of the daughter plus an α-particle; that is, Z = 2, A = 4. This technique was used in the discovery and identification of Sg (element 106) in 1974 by Ghiorso et al (29) and in the confirmation of that discovery by Gregorich et al (30) in 1994, using the production reaction 249 Cf + 18 O → 263 Sg + 4n. The α-decay sequence shown below was used to positively identify 263 Sg using this method, which is usually referred to as the "α-α correlation technique".…”

FutureMore "In-Depth" Chemical Studies Chemistry beyond Seaborgium? 93 NpIn keeping with the goal of the Viewpoints series of the Journal of Chemical Education, this article gives a 75-year perspective of the chemistry of the heaviest elements, including a 50-year retrospective view of past developments, a summary of current research achievements and applications, and some predictions about exciting, new developments that might be envisioned within the next 25 years. A historical perspective of the importance of chemical separations in the discoveries of the transuranium elements from neptunium (Z = 93) through mendelevium (Z = 101) is given. The development of techniques for studying the chemical properties of mendelevium and still heavier elements on the basis of measuring the radioactive decay of a single atom ("atom-at-a-time" chemistry) and combining the results of many separate experiments is reviewed. The influence of relativistic effects (expected to increase as Z 2 ) on chemical properties is discussed. The results from recent atom-at-a-time studies of the chemistry of the heaviest elements through seaborgium (Z = 106) are summarized and show that their properties cannot be readily predicted based on simple extrapolation from the properties of their lighter homologues in the periodic table. The prospects for extending chemical studies to still heavier elements than seaborgium are considered and appear promising.
