Abstract: [eng] [cze]
Ultra-weak spontaneous photon emission in visible range from palms and hands of dark-accommodated subjects has been measured every two hours in 5 experiments in the course of 24 hours by means of low-noise photomultiplier. Dorsal sides of the hands show higher fluctuations of photon emission intensity than palmar sides. Cycles of fluctuations of the 1 day, 6-8 hours and 3-4 hours long period have been observed from Fourier analysis of the measured data. Ultra-slabá spontanní emise fotonu ve viditelné oblasti byla měřena z dlaní a dorzálních stran lidských rukou každé 2 hodiny v 5 experimentech v rozsahu 24 hodin pomocí nízko šumového fotonásobiče. Dorzální strany rukou vykazují vyšší fluktuace intensity emise fotonu jako dlaně rukou. Z Fourierovy analýzy naměřených dat byly zjištěné cykly fluktuace emise s periodami 1 den, 6-8 hodin až 3-4 hodiny.
