I. S. Towner, E. Hagberg, J. C. Hardy, V. T. Koslowsky, G. Savard
Abstract
Data on superallowed Fermi beta decay in nuclei are compiled and electromagnetic corrections discussed. Recommended values for the weak vector coupling constant and the leading element of the Cabibbo-Kobayashi-Maskawa mixing matrix are given. Comments on neutron decay and limits extracted on extensions to the Standard Model are made.
