    "abstract": "The fine structure of histograms of measurements of 239Pu alpha-activity\nvaries periodically, and the period of these variations is equal to sidereal\nday (1436 minutes). The periodicity is not observed in the experiments with\ncollimator that restricts the alpha particles flow to be oriented to the Polar\nStar. Based on this study and other independent data, such as measurements\nconducted by the Arctic expedition, and similarity of the histograms in\nprocesses observed at different locations at the same local time, the\nconclusion was made, that the fine structure of statistical distributions of\nthe observed processes depends on the celestial sphere.",
