Method of multiple internal reflections in a description of nuclear decay

The space-time method of a description of a-decay of a nuclear with account of multiple internal reflections of wave packets in relation on boundaries of decay barrier. The method is based on the one-particle quantum mechanical model of the decay of a composite nuclear with a barrier. It allows to fulfill a non-stationary analysis of a-decay and to study in details this process at any time moment or point of space. According to the method, the nuclear makes oscilations some time in a beginning of the decay process and it need to account this time in calculating of time of the decay of the composite nuclear. The method, found on the multiple internal reflections, allows to determine this time in difference on other non-stationary methods and finds the time of the decay
