[Quantum transitions between states and cosmophysical fluctuations].

An explanation of the appearance of the reproducible fine structure of the histograms corresponding to different processes from simple chemical reactions to radioactive decays is developed. Earlier this explanation was reduced to extremely strong influence of small changes between energy levels of a quantum system under study and its environment on the transition probability of the system (chemical reaction, radioactive decay, e.t.c.) from the system last quantum state to final result of the studied process. In the present paper it is supposed that the main factors determining this probability is the periodical or quasi-periodical low frequency changes of local gravitational field leading to corresponding changes of the system mass (the quantum transition probability depends exponentially on the latter). This approach seems to able to propose non-contradictory explanation of many manifestations of macroscopic fluctuation.
