To construct a phase-equivalent energy-dependent local potential corresponding to a sum of local and nonlocal interactions, we use a simple method for expanding the wave function in a Taylor series up to the third order. We apply the constructed potentials to calculate the scattering phase shifts using the phase equation. The results for scattering in nucleon–nucleon, $\alpha$–nucleon, and $\alpha$–$\alpha$ systems agree reasonably well with the standard data.
Keywords: Coulomb–Yamaguchi potential, Taylor series expansion, phase-equivalent potentials, phase equation, nucleon–nucleon system, $\alpha$–nucleon system, $\alpha$–$\alpha$ system.
