Applied Physics and Mathematics Annotation << Back SPECTRUM OF SEISMIC RESPONSE TO SUPERNOVA OUTBURST SN1987A O.B. KHAVROSHKIN, V.V. TSYPLAKOV Variations in the analysis of gamma-radioactivity records have a wide range of periods (from several minutes to a day or more), all spectra contain reliable periods of their own solar oscillations (up to 40 periods), long solar periods are also found in the oscillations of the Earth and the Moon. The discovered effects of the interaction of the neutrino flux with gamma radiation sources will allow a deeper study of the Sun, Earth’s seismicity and other applied research. Further, this effect was called “anomalous neutrino radio-isotopic absorption”, (ANRI effect). The study of periodicities is most effective in monitoring γ-radioactivity. When using the ANRI effect, it is very important to know the value of the neutrino capture cross section with radioactive elements. Two methods are used to determine - one is the Cavendish scale, the other is thermal. The consideration and application of these two completely different methods for estimating the capture cross section, taking into account the unusual nature of the recorded ANRI effect, has become extremely important. The torsional balance of the Cavendish KVK allowed experimentally determining the cross section for the capture of radioactive isotopes when exposed to a solar neutrino flux (~ 10–12). The results obtained allowed us to move on to a new study — the characteristic features of the interaction of the neutrino flux from a supernova burst, the Sun and the Earth, and special detectors.
