An eikonal model has been used to assess the relationship between calculated strengths for first forbidden β decay and calculated cross sections for (p, n) charge exchange reactions. It is found that these are proportional for strong transitions, suggesting that hadronic charge exchange reactions may be useful in determining the spin-dipole matrix elements for astrophysically interesting leptonic transitions.
