ICP-SFMS search for long-lived naturally-occurring heavy, superheavy and superactinide nuclei compared to AMS experiments
A. Marinov, A. Pape, Y. Kashiv +4
Negative results obtained in AMS searches by Dellinger et al. on mostly unrefined ores have led them to conclude that the very heavy long-lived species found in chemically processe…
Enrichment of the Superheavy Element Rg in Natural Au
A. Marinov, A. Pape, D. Kolb +5
Based on the observation of the long-lived isotopes 261Rg and 265Rg (Z = 111, t(1/2) >= 10^(8) y) in natural Au, an experiment was performed to enrich Rg in 99.999% Au. 16 mg of Au…
Evidence for a long-lived superheavy nucleus with atomic mass number A=292 and atomic number Z=~122 in natural Th
A. Marinov, I. Rodushkin, D. Kolb +5
Evidence for the existence of a superheavy nucleus with atomic mass number A=292 and abundance (1-10)x10^(-12) relative to 232Th has been found in a study of natural Th using induc…
Existence of long-lived isotopes of a superheavy element in natural Au
A. Marinov, I. Rodushkin, A. Pape +7
Evidence for the existence of long-lived isotopes with atomic mass numbers 261 and 265 and abundance of (1-10)x10 relative to Au has been found in a study of natural Au usi…
Existence of long-lived isomeric states in naturally-occurring neutron-deficient Th isotopes
A. Marinov, I. Rodushkin, Y. Kashiv +7
Evidence for the existence of long-lived neutron-deficient isotopes has been found in a study of naturally-occurring Th using iductively coupled plasma-sector field mass spectromet…
The Chemical Separation of Eka-Hg from CERN W Targets in view of Recent Relativistic Calculations
D. Kolb, A. Marinov, G. W. A. Newton +1
In 1971 evidence for the production of element 112 via secondary reactions in CERN W targets was obtained. The evidence was mainly based on the observation of fission fragments in…
Super- and Hyperdeformed Isomeric States and Long-Lived Superheavy Elements
A. Marinov, S. Gelberg, D. Kolb +3
The recent discoveries of the long-lived high spin super- and hyperdeformed isomeric states and their unusual radioactive decay properties are described. Based on their existence a…
Study of Proton Induced Reactions in a Radioactive 129-I Target at Ep=660 MeV
V. S. Pronskikh, J. Adam, A. R. Balabekyan +19
Two NaI (85% 129-I and 15% 127-I) targets were exposed to a beam of 660-MeV protons. Cross sections for formation of 76 residual nuclei were obtained by the induced activity method…
New Outlook on the Possible Existence of Superheavy Elements in Nature
A. Marinov, S. Gelberg, D. Kolb +2
A consistent interpretation is given to some previously unexplained phenomena seen in nature in terms of the recently discovered long-lived high spin super- and hyper-deformed isom…
