“…The atomic number of the nucleus giving one of these tracks was estimated to be = -+ Z 119 6 10 with error bars assuming a 95% confidence degree. However, it seems that this information should be cross-checked thoroughly as the results reported by the other groups [47,51,52] did not show any hint for such a high flux of SHN in GCRs. The effect of the track fading during the 10 8 years space travel is not discussed in [54,55].…”

“…The controlled annealing method of olivine, originally developed by these authors, was of paramount importance for this study because the lengths of the annealed tracks of Z70 nuclei were reduced to fit the sub-millimeter dimensions of the olivine crystals extracted from the meteorite. The last papers published by this group [51,52] inform that about 1600 fossil tracks of the Th-U group nuclei were revealed in olivine taken from the Marjalahti and Eagle Station pallasite meteorites and estimate a limit of 3×10 −3 for a flux ratio of the SHE and Th-U nuclei in GCRs.…”

A fundamental outcome of modern nuclear microscopic theory is the prediction of the ‘islands of stability’ in the region of hypothetical superheavy elements (SHEs). In a heavy nucleus, going through the large-scale deformation on the way to fission, the motion of single nucleons is coupled with the collective degrees of freedom of the whole system. The most striking effect of this coupling is obtained for the case of fission of the heaviest nuclei, whose existence is defined entirely by the nuclear structure, i.e. by the shell effect. From this point of view, the synthesis and study of properties of superheavy nuclei (SHN) is a direct way for checking the basic statements of the microscopic nuclear theory. On the nuclide map, SHN outline the border of the heaviest nuclear masses. SHN set the limits of the periodic system of chemical elements. The study of possible existence of SHN in nature offers a way for testing different scenarios of astrophysical nucleosynthesis. The paper elucidates experimental approaches, used for testing the theory predictions made about the SHN, and presents the results of the discovery of the ‘stability island’ of SHEs.

“…They show different responses to different particles, filtering out the background of particles that would blur the tracks of particles or energies of interest. They have been used, for example, to find the exotic spontaneous emission of 14 C clusters by 223 Rn [5] or to find the long tracks produced by the natural decay of superheavy elements ( > 110) already disappeared [6]. Natural minerals are also useful for the fission track dating, oil search, and many other applications.…”

We consider a model made out of identical particles that repel each other with the Coulomb interaction. We study numerically and analytically the existence and properties of supersonic kinks, showing that they are very easy to be produced and propagate long distances. They have a wide range of velocities and energies. We are motivated by a special characteristic of the muscovite mica mineral. Tracks from particles such as muons can be distinguished in a complex decoration, but the only explanation to most of the tracks is localized excitations called quodons. They move in the cation lattice, sandwiched between the silicate layers, along the lattice directions. Quodons have also been observed experimentally [EPL 78 (2007)
