Radioactive decay seen as temporal canonical ensemble.

The operator of time formalism is applied to radioactive decay. It appears that the proposed approach offers a better insight and understanding of the phenomena in a way that the decay exponential-law becomes the Boltzmann distribution in Gibbs treatment of canonical ensemble. The radioactive decay is seen as temporal canonical ensemble where the radioactive constant appears as the analog of the absolute temperature multiplied by Boltzmann constant. The stochastic character of decay process becomes plausible in the proposed approach and the explanation why decay is characterized by fixed quantity, and not by some parameter, is offered.
