A dymamical theory of nuclear distortion leading fission, is presented. This theory is based on the unified model (the collective model). But, since spontaneous fission is an irreversible process, the theory is treated reflecting this speciality. Starting from this dynamical theory, a semi-empirical formula of spontaneous fission half lives of even-even nuclei is derived. This formula can well reproduce the general tendency of spontaneous fission half lives of even- even nuclei. The essential features which affect half lives are discussed. Finally, a reason for the asymmetry character of fission and the orientation in calculating the difference of half lives between even-even and even-odd nuclei are given. (auth)
