Alpha-particle production A common mode

Alpha-particle production a common mode of decay for radioactive nuclides in which the mass number changes. (21.1) Amine an organic base derived from ammonia in which one or more of the hydrogen atoms are replaced by organic groups. (7.6 22.4)...

An alpha particle, or a particle, is a helium nucleus ( He). Alpha-particle production is a very common mode of decay for heavy radioactive nuclides. For example, fU, the predominant isotope of natural uranium (99.3%), decays by a-particle production ... 

This is understood to mean that a neutron is absorbed by a nucleus of 13AI and gamma radiation is emitted, resulting in the formation of a product nucleus f Al. The product nucleus of a nuclear reaction can be either stable or radioactive. If the product nuclide is radioactive, it will eventually decay to a different nuclide. The most common modes of decay are emission of alpha particles, beta particles, and gamma rays other particles or radiations can also be emitted in radioactive decay, but they are of little analytical utility and will not be discussed here. Radioactive decay may involve a single-step transformation or may proceed through a series of steps. An example of the former is...
