Description
The Nuclear Incompressibility parameter is one of three important
components characterizing the nuclear equation of state. It has
crucial bearing on diverse nuclear and astrophysical phenomena,
including radii of neutron stars, strength of supernova collapse, emission
of neutrinos in supernova explosions, and collective flow in medium- and
high-energy nuclear collisions. In this talk I will review current
status of the research on direct experimental determination of nuclear
incompressibility via the compressional-mode giant resonances. In
particular,recent measurements on a series of Sn and Cd isotopes have provided an "experimental" value for the asymmetry term of nuclear
incompressibility. This
erm directly relates to properties of neutron stars. We also find that
the GMR centroid energies of the in both Sn and Cd isotopes are significantly lower than the theoretical predictions, pointing to the role of superfluidity and the MEM (Mutual Enhancement of Magicity) Effect.
