    "abstract": "As shown in the previous publications, the shape of the histograms\nconstructed by measurements of alpha-activity of samples of Pu-239, changes\nwith periods equal approximately 24 hours, 27 days, and a year. At a higher\nresolution each of these periods splits as a minimum in two components: daily\nperiod consists of two: sidereal day (1436 minutes) and solar day (1440\nminutes), 27-days period splits in 2 to 3 \"sub-periods\", and the yearly period\nappears to be a join of \"calendar\" period (which is equal to 1440 x 365 =\n525600 minutes) and \"solar\" period (equal to [(1440 x 365) + 369] =525969\nminutes). In the present paper results of more detailed research of this\nphenomenon are offered.",
