Anharmonic collective excitation in a solvable model
G. F. Bertsch, P. F. Bortignon, K. Hagino
We apply the time-dependent variational principle, the nuclear field theory, and the boson expansion method to the Lipkin model to discuss anharmonicities of collective vibrational…
Restoration of Isospin Symmetry in Highly Excited Nuclei
H. Sagawa, P. F. Bortignon, G. Colo`
Explicit relations between the isospin mixing probability, the spreading width of the Isobaric Analog State (IAS) and the statistical decay width of th…
Response function beyond mean field of neutron-rich nuclei
G. Colo`, P. F. Bortignon, R. A. Broglia
The damping of single-particle and collective motion in exotic isotopes is a new topic and its study may shed light on basic problems of nuclear dynamics. For instance, it is known…
Widths of Isobaric Analog Resonances: a microscopic approach
G. Colo`, H. Sagawa, N. Van Giai +2
A self-consistent particle-phonon coupling model is used to investigate the properties of the isobaric analog resonance in Bi. It is shown that quantitative agreement with…
