Valley of Beta Stability

(Beta-decay stable isobars, line of beta stability)
(set of isotopes not prone to beta decay)

The Valley of Beta Stability is a set of Isotopes (atomic-number/mass-number pairs) for which the balance of protons and neutrons does not induce typical Beta Decay, because they have sufficient Binding Energy. Such isotopes tend to be the ones we generally find, because if an isotope outside this set is created, it will beta decay until it reaches this set. As such, its existence is part of the theory explaining the Abundances of Elements.
