Description

The ways of transformation (self-organization) of nano-clusters into nano-structures depend not only on properties insulated nano-clusters and inter-cluster interplays, but also from methods of nano-cluster making. Our outcomes of searches of influencing of clustering on nuclear decay electron spectra in thin radioactive films are also endorsement to this. Radioactive sources can be produced by different methods: by the evaporation of radioactive solution drop on a platinum support, wetted insulin; by irradiation of mono-isotope vapor-deposited film in vacuo on aluminium support with neutrons; by vapor-deposition of certain radioactive isotope on aluminium support. Most neatly displays of atomic clusters (in the nanometre range) formation in a radioactive source solid-state matrix and nanostructures with a closed magnetic flux, i.e. in the form of toroids, were watched in the Lu→Yb and Lu→Hf decays. The radioactivity represented the Lu isotope fraction, isolated from the tantalum target, irradiated with protons with energy 660 MeV, and deposited by an electrolysis on platinum support (thickness 10 μm). Briefly our experimental data, their dynamic features are reduced to the following The internal conversion electron lines have composite structure varying with time. The M4- and M5-Auger-electron quantity exceeds (in tens of times) that, which one is conditioned by nuclear decay. This ratio shows time function. The auto emission spectrum electron line scission shows composite time function also. In the electron spectrum the display of the certain interference figure and asymmetrical satellite lines (having multipole dependence and varying with time) is watched. It testifies to the formation of toroids with inversely directional toroidal moments and interplay of angular momentums of ordered electrons with an external electromagnetic field. The experimental outcomes indicate the very significant role (during the cluster formation) of multipole electron radiation which is capable to transmit an angular momentum to atoms on the path of its propagation. The observation of orientation effects at registration of electrons in our spectrometer, finding out the time function and the energy threshold, testifies to formation in a near-surface layer of the structure, channeling the ordered electrons which are pulled out from 'traps'. As the energy threshold ≅210 keV, the structure interplanar interval is estimated as 1.5·1010 cm, i.e. considerably smaller, than, for example, in a W monocrystal (3·10-8 cm). The change of a spectrum of the ordered electrons is interesting in the energy threshold area: the ratio of registered electrons in the first counter and arranged after it the second one, greater diameter, sharply varies, that it is possible to consider as a visual display of angular momentum transfer by focalized electrons to atoms of working mixture of the counters and by un-sufficient spin correction of their focusing by the spectrometer magnetic field. Apparently, based on these facts it is possible to suspect, that we experimentally observe the dynamic nonintegrable system, in which one the Hamiltonian function cannot be expressed with the help of unitary transformations, and by virtue of symmetry violation by electromagnetic and weak interactions for its description it is necessary to use the mathematical apparatus including stochasticity, complexity, space parity violation and the time boom turn
