In this work, we study the elastic scattering of some light particles, such as ${}^2\mathrm{H}, {}^3\mathrm{H}, {}^3\mathrm{He}$, and ${}^4\mathrm{He}$, by heavy target nuclei with an extended Watanabe model, which uses as input the neutron-nucleus and proton-nucleus optical potentials and the ground-state wave functions of the projectile. The nucleon-nucleus optical potential used in this work was obtained within a semimicroscopic nuclear matter approach, whose real and imaginary parts are provided by the first- and second-order terms, respectively, of the Taylor expansion of the Brueckner-Hartree-Fock mass operator obtained with the reaction $G$ matrix built up with the Gogny force [J. Lopez Moraña and X. Viñas, J. Phys. G 48, 035104 (2021)]. The angular distributions of the scattering of ${}^2\mathrm{H}, {}^3\mathrm{H}, {}^3\mathrm{He}$, and ${}^4\mathrm{He}$ from different target nuclei and at different incident energies of the projectile computed with this model are analyzed. The reaction cross sections corresponding to some of these scattering processes are also calculated. Our results are compared with the experimental values as well as with another Watanabe calculation where the nucleon-nucleus optical potential is provided by the phenomenological Köning-Delaroche model. The limitations of the extended Watanabe model used in this work are also discussed.
