Angular distributions and Q-value spectra for transfer reactions in the systems ${}_{}{}^{36}{}_{}{}^{}\mathrm{S}$${+}^{144,154}$Sm have been measured at two energies close to the Coulomb barrier. Mass and charge identification was achieved using a time-of-flight system followed by an ionization chamber. Transfer probabilities were analyzed considering direct and sequential barrier penetration mechanisms. The dependence of the cross sections on the static quadrupole deformation of the targets was compared with the predictions of a semiclassical approach. The relative yields of the different channels were analyzed in the light of a random-walk approach based on the reaction Q values.
