摘要：
We have investigated the isoscalar giant monopole resonances (ISGMR) in Sn112-124 and Cd106-116 nuclei using inelastic scattering of 386-MeV a-particles at extremely forward angles, including 0 degrees. The strength distributions for various multipoles were extracted by a multipole decomposition analysis based on the expected angular distributions of the respective multipoles. From the ISGMR results, a value of K-T similar to -500 MeV is obtained for the asymmetry term in the nuclear incompressibility.
