We have investigated the isoscalar giant resonances in the Sn isotopes using inelastic scattering of 386-MeV $$alpha$$ particles at extremely forward angles, including 0$$^{circ}$$. The strength distributions for various multipoles were extracted by a multipole decomposition analysis based on the expected angular distributions of the respective multipoles. We find that the centroid energies of the isoscalar giant monopole resonance (ISGMR) in the Sn isotopes are significantly lower than the theoretical predictions. In addition, the asymmetry term, $$K_{tau}$$, in the expression for the nuclear incompressibility has been determined from the ISGMR data in Sn isotopes and is found to be consistent with a number of indirectly extracted values for this parameter.
