  主讲人简介:

 

  Umesh Garg, a professor of Physics at University of Notre Dame, graduated from Birla Institute of Technology and Science in Pilani, India, and obtained a Ph.D. in experimental nuclear physics from the State University of New York at Stony Brook. After postdoctoral work at the Cyclotron Institute, Texas A & M University, he joined the Notre Dame faculty in 1982. He has held visiting professorships at Vrije Universiteit, Amsterdam, the Netherlands; the Bhabha Atomic Atomic Research Center, Mumbai; RIKEN, Japan; and PKU, Beijing. He is a fellow of the American Physical Society and has served on the APS Governance Committee as well as the Program Committee of the APS Division of Nuclear Physics during 1995-997. He is currently a Guest Professor at PKU and an Adjunct Professor at TIFR, Mumbai.

 

  讲座内容摘要:

  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, and collective flow in medium- and high-energy nuclear collisions.  

 

  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). There have been some experimental results recently suggesting that nuclear structure effects may influence the energy of the isoscalar giant monopole resonance and, hence, the nuclear incompressibility. However, this being a bulk property of nuclear matter, one expects structure effects to play no role in it. 

 

  In this talk, I will review the current status of determination of nuclear incompressibility, and critically examine how, and if, nuclear structure effects play a role.
