Coupled channel calculations for heavy ion inelastic scattering can be alleviated through the use of integrals involving the product of two Coulomb functions, regular or irregular, with some inverse power of the radius, the range of the integration going from the point where the nuclear potential is weak to infinity. These integrals can be obtained by recurrence relations, starting with at most four of them which must be obtained by some method already described in the literature.
