</span>The Nuclear Incompressibility parameter is one of three important<br>
components characterizing the nuclear equation of state (EOS). It has<br>
crucial bearing on diverse nuclear and astrophysical phenomena,<br>
including radii of neutron stars, strength of supernova collapse, emission<br>
of neutrinos in supernova explosions, and collective flow in medium- and<br>
high-energy nuclear collisions. In this talk I will review current<br>
status of the research on direct experimental determination of nuclear<br>
incompressibility via the compressional-mode giant resonances. In particular,<br>
measurements on a series of Tin and Cadmium isotopes have provided an<br>
"experimental" value for the asymmetry term of nuclear incompressibility, which <br>
can provide constraints on the EOS of neutron stars.<o:p></o:p></p>
