Power Spectrum Analysis of LMSU (Lomonosov Moscow State University) Nuclear Decay-Rate Data: Further Indication of r-Mode Oscillations in an Inner Solar Tachocline
This article presents a power-spectrum analysis of 2,350 measurements of the
Sr/Y decay process acquired over the interval 4 August 2002 to 6
February 2009 at the Lomonosov Moscow State University (LMSU). As we have found
for other long sequences of decay measurements, the power spectrum is dominated
by a very strong annual oscillation. However, we also find a set of
low-frequency peaks, ranging from 0.26 year to 3.98 year, which
are very similar to an array of peaks in a power spectrum formed from Mt Wilson
solar diameter measurements. The Mt Wilson measurements have been interpreted
in terms of r-mode oscillations in a region where the sidereal rotation
frequency is 12.08 year. We find that the LMSU measurements may also be
attributed to the same type of r-mode oscillations in a solar region with the
same sidereal rotation frequency. We propose that these oscillations occur in
an inner tachocline that separates the radiative zone from a more slowly
rotating solar core.Comment: 5 pages, 8 figures. v2 corrects three typographical errors on page 3,

The outcomes of researches of the processes course in various systems are considered. The separation of the detected phenomena on three groups is justified: 1) Unusually large fluctuations of parameters describing of the processes course in physical, chemical, biological and other complicated systems. The processes course in such systems has chaotic, splash and fractal character. 2) The variability of the processes intensity in systems consisting of independent elements (for example, nuclei in radioactive substance). In such systems the smooth rhythmic modifications and short splashes are found. 3) The variability of distribution of values, obtained at multiple measurements, even if an average rate of process is constant. Such modifications, having the space rhythmic changes and also connected with artificial actions, are found out. The first group of phenomena is connected to the presence in complicated systems of the large number of the interconnected elements, capable to accumulate and to emit an energy, that is the reason of sensitivity of processes in such systems to exterior actions possessing a series of paradoxical properties (for example, high sensitivity to weak actions and weak response to powerful actions). It is possible to explain the second group of phenomena by operation of the exterior agent, capable to influence the probability of processes in each of the independent elements. The third group of phenomena probably indicates the information interactions existence.Π Π°ΡΡΠΌΠΎΡΡΠ΅Π½Ρ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠΉ Ρ

Search for the time dependence of the 137Cs decay constant
Starting from June 2011, the activity of a 137Cs source has been measured by
means of a HPGe detector installed deep underground in the Gran Sasso
Laboratory. In total about 5100 energy spectra, one hour measuring time each,
have been collected. These data allowed the search for time variations of the
decay constant with periods from a few hours to 1 year. No signal with
amplitude larger than 9.6{\cdot}10-5 at 95% C.L. has been detected. These
limits are more than one order of magnitude lower than the values on the
oscillation amplitude reported in literature. In particular, for 1 year period
an oscillation amplitude larger than 8.5{\cdot}10-5 has been excluded at 95%
C.L., independently of the phase. The same data give a value of 29.96{\pm}0.08
years for the 137Cs half life, in good agreement with the world mean value of
30.05{\pm}0.08 years.Comment: 5 pages, 4 figure
