Isotopic Dependence of the Giant Monopole Resonance in the Even- A Sn112–124 Isotopes and the Asymmetry Term in Nuclear Incompressibility
Year: 2007
Type: article
Abstract: 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 $\ensuremath{\alpha}$ particles in the angular range 0\ifmmode^\circ\else\textdegree\fi{}--8.5\ifmmode^\circ\else\textdegree\fi{}. 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 $^{208}\mathrm{Pb}$ and $^{90}\mathrm{Zr}$ very well. From the GMR data, a value of ${K}_{\ensuremath{\tau}}=\ensuremath{-}550\ifmmode\pm\else\textpm\fi{}100\text{ }\text{ }\mathrm{MeV}$ is obtained for the asymmetry term in the nuclear incompressibility.
