Transfer cross section angular distribution data for the stripping of two protons and one alpha particle are studied for the {sup 16}O + {sup A}Sm systems (A = 144, 148, 150, 152 and 154), at energies slightly lower than the Coulomb barriers and angles up to 0 = 170{degrees}. From a semiclassical formalism, transfer and elastic scattering data, the transfer form factors is derived. For only one of the ten channels studied there are signatures for the interpretation that the transfer reaction mechanism at backward angles, corresponding to small distances, may behave as a multi-step process leading to fusion. Coupled channel calculations including transfer channels are performed for the study of the sub-barrier fusion of these systems. The influence of short distance transfer reactions on the fusion is discussed. For these and other systems, the conclusions from this approach are found t to long range fusion absorptive potentials.
