Search for superheavy elements in nature
2014 Superheavy elements have been searched for by neutron induced fission of mass separated samples. Various natural materials have been investigated : minerals, manganese nodules, lunar dust, meteoritic materials. Fissioning masses have been collected in the A = 300 mass region. However, one cannot conclude that these masses are superheavy elements because of a possible contamination of this ...
متن کاملSearch for Superheavy Elements among Fossil Fission Tracks in Zircon
Fossil tracks with long ranges were found in some crystals of natural zircons. Their length is 120 to 200% of that of uranium fission tracks in zircon. A few of the developed fossil tracks are also 3 to 4 times as wide as fission tracks from uranium (observed in the same crystal). The long and/or fat tracks could be explained as having resulted from fission of several superheavy elements from t...
متن کاملAdsorption Studies with Homologs of Superheavy Elements
In preparation of chemical studies with superheavy elements around Z = 114, the adsorption behavior of these elements and their lighter homologs on different metals has been predicted based on (semi-)empirical models and extrapolations (see e.g. [1, 2]). Adsorption studies with SHE homologs were performed on various metals, especially metals of group 10 and 11 (see e.g. [3]). The experimental r...
متن کاملThe Scintillation Counter
The development of detectors for both counting and measuring the energy of particles and photons has played an important role in the evolution of nuclear physics. In this experiment, you will be introduced to one such detector the scintillation counter which is particularly suitable for detecting γ-ray photons. You will use it to observe the energy spectrum of γ-rays from several nuclei and stu...
متن کاملChemistry of superheavy elements.
The number of chemical elements has increased considerably in the last few decades. Most excitingly, these heaviest, man-made elements at the far-end of the Periodic Table are located in the area of the long-awaited superheavy elements. While physical techniques currently play a leading role in these discoveries, the chemistry of superheavy elements is now beginning to be developed. Advanced an...
