Cosmo-physical effects in structure of the daily and yearly periods of change in the shape of the histograms constructed by results of measurements of alpha-activity Pu-239

As shown in the previous publications, the shape of the histograms constructed by measurements of alpha-activity of samples of Pu-239, changes with periods equal approximately 24 hours, 27 days, and a year. At a higher resolution each of these periods splits as a minimum in two components: daily period consists of two: sidereal day (1436 minutes) and solar day (1440 minutes), 27-days period splits in 2 to 3 "sub-periods", and the yearly period appears to be a join of "calendar" period (which is equal to 1440 x 365 = 525600 minutes) and "solar" period (equal to [(1440 x 365) + 369] =525969 minutes). In the present paper results of more detailed research of this phenomenon are offered.

Experiments with rotating collimators cutting out pencil of alpha-particles at radioactive decay of Pu-239 evidence sharp anisotropy of space

As shown in our previous experiments fine structure of histograms of alpha-activity measurements serve as a sensitive tool for investigation of cosmo-physical influences. Particularly, the histograms structure is changed with the period equal to sidereal (1436 min) and solar (1440) day. It is similar with the high probability in different geographic points at the same local (longitude) time. More recently investigations were carried out with collimators, cutting out separate flows of total alpha-particles flying out at radioactive decay of 239Pu. These experiments revealed sharp dependence the histogram structure on the direction of alpha-particles flow. In the presented work measurements were made with collimators rotating in the plane of sky equator. It was shown that during rotation the shape of histograms changes with periods determined by number of revolution. These results correspond to the assumption that the histogram shapes are determined by a picture of the celestial sphere, and also by interposition of the Earth, the Sun and the Moon.
