Physical Principles & Numerical Solution
Alpha decay or \alpha-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and
thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.
