The mechanism allowing a stabilization of exited states of quantum systems is suggested. The stabilization mechanism is similar to the quantum Zeno-s effect. The difference is that the system is not the subject of an observation. Instead of that the system is periodically transferred to another quantum state. The rate of the transitions necessary for the stabilization is determined. As an example the opportunity of suppression of radiation in synchrotrons is shown. The experiment is briefly described, in which the mechanism quantum whirligig was probably observed. The article is constructed as follows. In introduction the basic features of quantum Zeno effect are briefly described and the basic differences of the offered mechanism (mechanism of quantum whirligig) from quantum Zeno effect are formulated. In the first section the simplest model of quantum system is formulated, in which the offered mechanisms of stabilization of the excited states (mechanism of quantum whirligig) can be realized. It is important, that these models except their simplicity allow to receive the rigorous solutions. These strict solutions are received in section 2. In first and in the second sections are considered only induced processes. In the third section the opportunity of suppression synchrotron radiation is shown. In this section except induced transitions are analyzed and spontaneous transitions. In the fourth section the results of experiments on influence of external influence on processes of disintegration radioactive isomer of Hff-178 are briefly described. The reasons are expressed, that the observable results can be explained by the mechanism of quantum whirligig. In the fifth section is shown, that the mechanism of quantum whirligig can be realized not only in quantum systems, but also in classical. In the conclusion the key points for use of the mechanism quantum whirligig for stabilization of the excited states are formulated.
