Description

Giant resonances are highly collective states of nuclear vibration. The compressional-mode giant resonances provide the only direct experimental measurement of the nuclear incompressibility, a fundamental property of nuclear matter that is crucial to understanding of a number of nuclear and astrophysical phenomena, including strength of collapse in supernovae explosions, collective-flow in high-energy heavy ion collisions, and properties of neutron stars the largest nuclei that exist in nature. Prof. Garg s group has been investigating the Isoscalar Giant Dipole Resonance, an exotic compressional-oscillation, also referred to as the squeezing mode . Dr. Tao li designed a sophisticated experiment to measure the giant resonances of Sn even isotopes between 112 and 124. The experiment is performed at RCNP, Osaka, Japan, in which a high resolution "Grand Raiden" is capable to take such high resolution measurement. Some computational methods, and programming code was developed by Dr. Li to analyze the data. The result gives us the better understanding to the nuclear impressionability, which is a ground stone of the nuclei.
