However the nucleus can also end up in a higher energy state after colliding with another nucleus or being struck by a neutron. Alpha decay or α-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. A heavy isotope is more likely to undergo beta decay, with one of the excessive neutrons transforming into an additional proton in the nucleus, moving the nucleus on step to the right in the Periodic Table, with no change in mass number.
