### Abstract

We use a 4Ω shell-model calculation with a two-body effective interaction derived microscopically from the Reid93 potential to calculate the isospin-mixing correction for the ^{10}C→^{10}B superallowed Fermi transition. The effective interaction takes into account the Coulomb potential as well as the charge dependence of T = 1 partial waves. Our results suggest the isospin-mixing correction δ_{C} ≈ 0.1%, which is compatible with previous calculations obtained by other methods. The obtained δ_{C} correction is about a factor of four too small to obtain unitarity of the Cabibbo-Kobayashi-Maskawa matrix with the present experimental data.
