Quasi-particle properties and Cooper pairing in trapped Fermi gases
L. Giorgetti, L. Viverit, G. Gori +3
The possibility for the particles in a Fermi gas to emit and reabsorb density and spin fluctuations gives rise to an effective mass and to a lifetime of the quasi-particles, as wel…
Gamma-ray strength functions in thermally excited rotating nuclei
T. Dossing, B. Herskind, A. Maj +5
A general discussion and illustration is given of strength functions for rotational transitions in two-dimensional E(gamma_1) x E(gamma_2) spectra. Especially, a narrow component s…
Probing the width of compound states with rotational gamma rays
M. Matsuo, T. Døssing, B. Herskind +3
The intrinsic width of (multiparticle-multihole) compound states is an elusive quantity, of difficult direct access, as it is masked by damping mechanisms which control the collect…
On the Origin of Nuclear Superfluidity
F. Barranco, R. A. Broglia, G. Gori +3
The induced pairing interaction arising from the exchange of collective surface vibrations among nucleons moving in time reversal states close to the Fermi energy is found to lead…
