Phys. Rev. Lett. 62, 866–869 (1989)Corrections to the Fermi Matrix Element for Superallowed β DecaySee Also: Erratum Received 10 February 1988; revised 5 December 1988; published in the issue dated 20 February 1989 Corrections to the Fermi matrix element for superallowed transitions due to isospin nonconservation are reexamined. The sources of theoretical uncertainty and the possibility of a previously neglected correction based on the mismatch between the spectator nucleons are investigated. The consequences to the conserved-vector-current hypothesis and the Kobayashi-Maskawa mixing angles are discussed. © 1989 The American Physical Society URL:
