The coalescence model for complex-particle emission is modified by introducing corrections for the Coulomb barrier and the binding energy of the ejectile. The model is applied to the analysis of deuteron spectra for various projectile-target combinations at incident energies of 15-25 MeV/nucleon. The results, together with those of a previous analysis of alpha -particle spectra for the same colliding systems, show that the extracted coalescence radii decrease regularly with increasing A<sub>p</sub>/(A<sub>p</sub>+A<sub>T</sub>) for both the weakly bound deuterons and the strongly bound alpha particles.
