Abstract

The elastic scattering cross section of 92Mo(α,α)92Mo has been measured at energies of Ec.m. ≈ 13, 16, and 19 MeV in a wide angular range. The real and imaginary parts of the optical potential for the system 92Mo-α have been derived at energies around and below the Coulomb barrier. The result fits into the systematic behavior of α-nucleus folding potentials. The astrophysically relevant 96Ru(γ, α)92Mo reaction rates at T9 = 2.0 and T9= 3.0 could be determined to an accuracy of about 16% and are compared to previously published theoretical rates.
