The direct part of real 𝛼−𝛼 interaction potential is calculated in the simple folding model using density-dependent Brink–Boeker effective interaction. The simple folding potentials calculated from the short- and finite-range components of this effective interaction are compared with their corresponding double folding results obtained from the oscillator model wave function to establish the relative accuracy of the model. It is found that the direct part of real 𝛼–𝛼 interaction potential calculated in the simple folding model is reliable.
