Two-body scattering is studied by solving the Lippmann-Schwinger equation in momentum space without angular-momentum decomposition for a local spin-dependent short-range interaction plus Coulomb. The screening and renormalization approach is employed to treat the Coulomb interaction. Benchmark calculations are performed by comparing our procedure with partial-wave calculations in configuration space for $p\text{−}{}^{10}\mathrm{Be},p\text{−}{}^{16}\mathrm{O}$, and ${}^{12}\mathrm{C}\text{−}{}^{10}\mathrm{Be}$ elastic scattering, using a simple optical potential model.
