The angular distribution of differential cross sections for α and ${}^3\mathrm{He}$ projectiles elastically scattered from ${}^{12}\mathrm{C}$ and ${}^{16}\mathrm{O}$ are calculated at the energy range from 25 to 217 MeV. The double folding model with an energy-target density dependent Jeukenne, Lejeune, and Mahaux effective nucleon-nucleon interaction is used to obtain both real and imaginary parts of the central optical potential. The dependence of the potential on densities of projectile and target nuclei in a factorized form is considered. Good fits to the experimental data are obtained. Nuclear rainbow scattering is also observed and discussed.
