Nuclear Incompressibility and the Asymmetry Term from Measurements of the Giant Monopole Resonance in Neutron-Rich Nuclei

The nuclear incompressibility parameter, K_∞, is one of three important components characterizing the nuclear equation of state, with crucial bearing on diverse nuclear and astrophysical phenomena. The only direct experimental measurement of this quantity comes from the compression-mode giant resonances—the isoscalar giant monopole resonance (ISGMR) and the isoscalar giant dipole resonance (ISGDR).

In this talk, I will review the current status of determination of nuclear incompressibility, especially its asymmetry term, and discuss recent and forthcoming measurements on the ISGMR in neutron-rich nuclei, including an approved experiment on ¹³²Sn at FRIB.
