On experimental determination of the kind of the decay law at a short period of detection

A number of theories predict the deviations from the exponential decay for short detection times t/T1/2→O: either short-period oscillations or decay deceleration (Zenon quantum effect) are expected. The experimental data of this paper and the literary data are used to analyze the degree of experimental research of the type of the decay law for the nuclei of one ''age'' for detection period 10-10< or approx. t/T1/2 < or approx.10-1. It is shown that the available experimental data do not permit to speak about the detecting (in this time range) of deviations from exponentiality the etails of experiments are discussed
