The volume integrals of the DELTA --nucleon potentials in the triplet and singlet spin states are deduced from hyperfragment binding-energy data. The effects of tensor forces are neglected in the calculation but are discussed qualitatively. Results are sensitive to the sizes and shapes of the nuclei in which the DELTA is bound, but are not very sensitive to A binding energies. Results also depend on the range of the DELTA -nucleon potential and on the spin configurations of the nuclei. Within the approximations made, the A --nucleon potentials are consistent with experiment and agree with theoretical potentials due to pion exchange. A crude determination of the DELTA --nucleon potential from the observed lifetime for mesonic decay of hyperfragments is consistent with the binding-energy determination. (auth)
