Title:  Compressional-mode Giant Resonances and
	the Nuclear Incompressibility

Date:   22nd Feb. 2002 (Fri.) 15:00 -

Place:  RIKEN Main Bldg. 2F Seminar Room

Abstract:
Nuclear Incompressibility is a key component of the nuclear equation of
state, with crucial implications on our understanding of diverse nuclear
and astrophysical phenomema such as stellar formation, supernova
explosions, and collective flow in heavy-ion collisions.
The only direct experimental measurements of nuclear incompressibility
come from the compressional-mode giant resonances: the Giant Monopole 
Resonance and the {\em Isoscalar} Giant Dipole Resonance (ISGDR). 
In this talk, the current status of experimental work on the ISGDR, 
an exotic mode of nuclear oscillation, will be reviewd. Results from 
recent measurements at RCNP, using small-angle inelastic scattering of 
400 MeV $\alpha$ particles, will be presented and the implications on 
determination of nuclear incompressibility will be discussed.
