Angular distribution for the elastic scattering of 36 MeV alpha particles from gold target has been measured fromϑ ∼ 10–56°. The cross-section data have been analyzed in terms of the optical model. The real part of the optical model potential (VR) has been deduced by two prescriptions: (i) combining the volume integral, the radius at whichVR=2.4 MeV and the slope at this radius (1/VR) (dVR/dr) (ii) combining the volume integral, the root mean square radius and the equivalent sharp radius systematics. The imaginary potential depth has been searched to fit the data. The prediction using (i) for the real potential fits the data the best.
