• A new time-dependent treatment of nuclear reactions is given, in which the wave function of compound nucleus is expanded by a sequential series of the reaction processes. The wave functions of the sequential series form another complete set of compound nucleus at the limit Δt→0. It is pointed out that the wave function is characterized by the quantities : the number of degrees of freedom of motion n, the period of the motion (Poincare cycle) t_n, the delay time t_<nμ> and the relaxation time τ_n to the equilibrium of compound nucleus, instead of the usual quantum number λ, the energy eigenvalue E_λ and the total width T_λ of resonance levels, respectively. The transition matrix elements and the yields of nuclear reactions also become the functions of time given by the Fourier transform of the usual ones. The Poincare cycles of compound nuclei are compared with the observed correlations among resonance levels, which are about 10^<-17>〜10^<-16> sec for medium and heavy nuclei and about 10^<-20> sec for the intermediate resonances.
