International audience Mass-energy and angular distributions of fission fragments for the $^{48}$Ca+$^{144,154}$Sm \to $^{192,202}$Pb, $^{40}$Ca+$^{154}$Sm \to $^{194}$Pb reactions have been measured. Fusion suppression and the presence of quasi-fission at energies near and below the Coulomb barrier have been observed for the reactions with the deformed target $^{154}$Sm. In the case of the spherical $^{144}$Sm target no evidence of quasi-fission has been found.
