Dissipation-fluctuation dynamics of fusion-fission reactions and synthesis of superheavy elements
Dynamical treatments of fission processes are briefly reviewed with an emphasis on the strong dissipation or friction for collective motions of nuclei in high excitation. The theories are applied to synthesis of superheavy elements. Characteristic features of formation and surviving are discussed with reference to possible incident channels. Theoretical prediction are presented on favorable inc...
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 کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولOn Theoretical Problems in Synthesis of Superheavy Elements
Predictions and structure studies of superheavy elements (SHE) have been made, since the establishment of the nuclear shell model[1]. Especially in the last decade, elaborate investigations have been performed of shell correction energy and thereby of a possible location of the superheavy island in the nuclear chart. Furthermore, not only about the center of the island, but also about stability...
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...
