摘要：

The alpha-particle spectra at different laboratory angles were measured from the fusion reaction Al-27 + Si-28 at E(lab) = 140.0 MeV. These spectra deviate at both higher and lower energies from theoretical calculations using RLDM moments of inertia. In order to explain the experimental spectra changes were required in the emission barriers and moments of inertia corresponding to large nuclear deformations.
