Theoretical support for the $π(1300)$ and the recently claimed $f_0(1790)$ as molecular resonances
2011/7/20
A study of three-pseudoscalar $\pi K \bar{K}$ and $\pi \pi \eta$ coupled system is made by solving the Faddeev equations within an approach based on unitary chiral dynamics.
Emergence of pygmy dipole resonances: Magic numbers and neutron skins
pygmy dipole resonances Magic numbers neutron skins
2011/7/20
The pygmy dipole resonances (PDR) for even-even nuclei in 8=re studied performing a systematic calculation of the random-phase approximation with the Skyrme functional of SkM*. The calculation...
Gradient Catastrophe and Fermi Edge Resonances in Fermi Gas
Gradient Catastrophe Fermi Edge Resonances Fermi Gas
2010/11/19
A smooth spatial disturbance of the Fermi surface in a Fermi gas inevitably becomes sharp. This
phenomenon, called the gradient catastrophe, causes the breakdown of a Fermi sea to disconnected parts ...
Probing Nuclear Symmetry Energy with Giant Dipole Resonances in Finite Nuclei
symmetry energy dipole resonance Pygmy resonance
2009/11/18
The relationship between the centroid energies of the isovector giant dipole resonance of finite nuclei and the symmetry energy has been studied. It is found the excitation energies of the dipole reso...
Dynamically generated resonances
dynamically generated resonances chiral dynamics hidden gauge formalism for vector meson interaction
2009/11/17
In this talk I report on recent work related to the dynamical generation of
baryonic resonances, some made up from pseudoscalar meson-baryon, others from vector meson-baryon and a third type from two...
Study of Proton Resonances in 22Mg by Resonant Elastic Scattering of 21Na+p and Its Astrophysical Implication

2009/10/29
Proton resonant states in 22Mg have been investigated by the resonant elastic scattering of 21Na+p. The 21Na beam with a mean energy of 4.00 MeV/u was separated by the CNS radioactive ion beam separat...
