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 $\alpha$ particles in the angular range $0^\circ$--$8.5^\circ$. 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 $^{208}$Pb and $^{90}$Zr very well. From the GMR data, a value of $K_{\tau} = -550 \pm 100$ MeV is obtained for the asymmetry-term in the nuclear incompressibility.

  1. A Gaussian Process framework for constraining the nuclear equation of state from microscopic calculations with correlated uncertainties

    nucl-th 2026-08 conditional novelty 6.0 of 10

    GPDiff fits a hierarchical Gaussian process to microscopic asymmetric-matter energies and propagates correlated uncertainties to EOS parameters and neutron-star matter properties.

  2. Extended Skyrme effective interactions with higher-order momentum-dependence for transport models and neutron stars

    nucl-th 2024-12 conditional novelty 6.0 of 10

    The authors generalize the Skyrme pseudopotential to N5LO with p^10 momentum dependence, fit it to the optical potential up to 2 GeV, and show the resulting interactions reproduce HADES proton flow data.
