The strength distributions of the giant monopole resonance (GMR) have been measured in the even-A Sn isotopes (A=112-124) with inelastic scattering of 400-MeV {alpha} particles in the angular range 0 deg. - 8.5 deg. We find that the experimentally observed GMR energies of the Sn isotopes are lower than the values predicted by theoretical calculations that reproduce the GMR energies in {sup 208}Pb and {sup 90}Zr very well. From the GMR data, a value of K{sub {tau}}=-550{+-}100 MeV is obtained for the asymmetry term in the nuclear incompressibility.
