#Fission equation plus
In the case of Cf-252, the two mass numbers plus any neutrons released will always add up to 252, the mass number of the californium. There are two peaks, one for the heavier fragment and one for the lighter. You will be looking at a mass distribution curve for the SF of Cf-252. Go here after reading the rest of the paragraph. How do you know what decay products are produced? A very good question! Nothing starts the SF from outside, the decay originates from internal imbalances.Įnergy is also produced when a nuclide undergoes SF, this is typically not shown in the equation. Note that the atomic number is the same on both sides as well as the mass number totalling up to be the same on each side. In the region near 230, SF can be quite rare while in the upper regions (a 254, for example), SF is usually the most common form of decay. A percentage of the time, they decay by spontaneous fission. Some by beta decay, some by positron, etc. These nuclei are unstable and decay by different forms of radioactive decay. Spontaneous fission (SF) happens in heavier elements, those with atomic numbers greater than 89 and mass numbers of about 230 and above.
