The asymmetry term in the nuclear-matter incompressibility from measurements on the giant monopole resonance: An Update

Abstract

We have investigated the isoscalar giant monopole resonances (ISGMR) in ${}^{112-124}$Sn and ${}^{106-116}$Cd nuclei 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. From the ISGMR results, a value of $K_{\tau }\sim -500$ MeV is obtained for the asymmetry term in the nuclear incompressibility.
