Mirror beta decays
Abstract
Beta decays of mirror nuclei differ in Q-value, but will otherwise proceed with transitions of similar strength. The current status is reviewed: Fermi transitions are all very similar, whereas Gamow–Teller transitions can differ in strength by more than a factor two. Several effects that can contribute to the asymmetries are discussed, the largest effect appears to be due to binding-energy differences between the mirror systems. Recommendations are given for future experimental investigations.
