Fission rate formula

WebThe probability of spontaneous fission is very strongly dependent upon, and increases rapidly with, the atomic number of the heavy element. For example, 230 Th, which has Z = 90, has a half-life for spontaneous fission of approximately 1.5 × 10 17 years, whereas for 254 Cf, which has Z = 98, the half-life is about 60 days for this mode of decay.
