Abstract : Considerable corrections to the ft values (2 to 9%) emerge when taking into account the small components of the nuclear wave functions in the calculations of the matrix elements <1> and <sigma>. The calculations are performed for several relativistic single-particle models; the resulting potential well parameters are in agreement with values which one currently obtains in non-relativistic calculations. The corrections turn out to be rather model independent. Coulomb distortion of the proton wave is included in the computation, but its effect is small. (Author)
