Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

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.
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 possible role of
superfluidity and the MEM (Mutual Enhancement of Magicity) Effect.
